Hey Joes,
Arhus was *the place* and those who were there know it. What i think is
particularly nice about this location is that many Euro-Joes could
attend who had no chance of such a meeting ever before. We could drive
by car and bring lots of gear (will increase next year!).
If the location was Hawaii, however a beautiful place it is, only 20
people could come and bring only little gear on the plane.
The only possible improvement was if Eriksminde Efterskole was rebuilt
in northern germany - more centrally located, you know :-).
Seriously, it was one hell of an event. Munich would be OK for me too -
meet in Hartmut's living room... <g>. I bet the Munich Triode Mafia is
already working on it.
We should set up an open-air area for next year. I volunteer for the
midrange speakers.
<BG>
For our Australian and American friends, wouldn't it be an idea to set
up a meeting within solid area (=you can drive) ? NY-Noise-Forte
(extended)... ? Melbourne Audio Meeting (aka MAM) ?
see you
Timo

Hello Joes!
I arrived at home again after a SUPER weekend at Eriksminde Efterskole
with Kurt and the other Joes!
I wish to thank Kurt and his Friends and Family for making this event
possible and run SO smoothly!
It was very nice to meet you (Joes), discuss and work with you and
listen to all the coooooooool gear that was there.
For the poor people who were not there, i have made some notes about the
stuff that i listened to and my impressions about it. There are also
some notes about the lectures and workshops which took place.
I wish i had taken more comprehensive notes about some lectures, and the
drawings which i made to go with them are missing as well.
<< start notes >>
I and Manfred had the first system running. We used Surt and his EC8020
alternatingly and his tubed Cara CD Player on Tannoy 15'' super gold
speakers. sounded just fine. surt had better bass and less treble (imp.)
which i liked better.
Evening meal with Manfred, Jeremy and their families.
long night talking with the joes.
Jeremy's 2A3 "free lunch" with the tannoys.
FI super X 2A3 amp on tannoys, fine. treble not as sharp as w ec8020.
Thomas Meyer's RIAA, Tannoys with invisible speaker cable.
Hartmut's demonstration : Scheu TT Acryl platter.
comprehensive explanation of the Scheu and comparison to other TTs.
Manfred : async motor can not oscillate.
Demo of scheu + thomas riaa, ec8020, tannoys : excellent. definitely
different sounding compared to cd on the same system. it really sounds
more analog, keeping in mind that the real world IS analog.
really enjoyed this session with music by Thomas M. very natural and
fun.
after some more listening i think this is the best sound of the show so
far.
Lecture by hartmut about kaneda pre. demo w same spk, amp, tt.
After Hartmut explained that this was about transistors all but three
people left the room :-(( !
Oris 150, bass: 8x 13cm per channel, Guido's modified TEAC CD Player,,
sounds nice.
lacking in the bass.
fantastic mid/treble integration and dynamics in this range.
not harsh, no edge.
same system as on the tannoys: oris more lifelike and dynamic but worse
bass.
SE OPTs by Michal Ulbrich, with Jeremy's 2A3.
Most gorgeous looking OPTs i have ever seen!
silver foil cables noticeably better than Allen's simpler design (centr
cond, ptfe tube, braid).
Kurts DECCA: excellent on his tannoys!
Cable Workshop with Allen, worked with Guido. Interesting insights to
cable development and production.
Ortofon Tech surprisingly recommends Tripath amps.
Magnificator horn system : very nice bass/mid integration, though not
very low bass. problem : 3-way drivers too far apart.
Lecture by TD and Kurt, use current amps with high output Z. no
distorted back emf feedback.
Fantastic slide show, very nice photographs, skillful arrangement and
nice rock music selection.
Rick's 417 0.5w parafeed on Guido's Audionote speakers 89db. no worries.
listening session with my hybrid.
allen : neat!
no bad comments
cool light effects
sadly the tda2050 didn' work, distortion appeared when right vol was
turned up.
i noticed some people have very narrow ideas of systems, they are very
selective. i like the spontaeous approach much more like "no problem
lets hook it up and see if it goes up in smoke". this is fun, the other
way it is dreadful work. it is no matter if a tried system does not
work, it actually happened to me, but at least we gave it a shot and
were relaxed about it, not tense as some other guys.
Guido Tent's PS filtering seminar:
second cap big
smaller choke
higher dcr => damping
PSU workshop
my hybrid w tannoy+altec system on the tannoys. Nice bass. The hybrid
does surprisingly well covering below 1khz considering it is only a 5
watt amp. there were no complaints about it and Mattjies and Jim seemed
to like it. They asked me put it in the system.
Remco and i tried to set up the AKSA with my PSU but it didn't work,
most likely because we had only half the recommended supply voltage.
<< end notes >>
These are just my notes straight out of my palmtop computer (i hope i
didn't annoy anyone by scrabbling on it all the time).
Maybe you can make sense of it - maybe not.
SEE YOU AGAIN NEXT YEAR :-)

Thanks ! I have to add that the TEAC (thoug modified) only served as a

Has anyone ever heard the TAD 1201 carbon fiber (black 12" mid of about 99db
efficiency--intended to cover 200 to 3K) in a system or seen a subjective
review of it? I realize the thing is a bit huge by normal standards, but
they've been carrying it for eons and I've never heard or seen a reference to
how it sounds.

Hey! Now you got me thinking! Have you seen what B&W has done with the
Nautilus drivers? A long tapered transmission line... Well, why not build one
for the TAD compression driver? Seems to me it might be a very low compromise
solution : )...
I'm going to try it..

The Nickster has added TAD to his website, so I'll se if I can get him
to include some internal pix of the beastie. (Nude, of course!*) Mmmm,

Hello,
This is IMHO a very good solution.
The famous Iwata a specialist of pressure in tunnels, guns silencers and
horns (the most dynamical horns I ever listened too) use such method to
load the rear of the diaphragms of his comprssion drivers. There was a
paper in the French review l'Audiophile. The length of the tubes he used
were between .5 meter to several meters depending on the frequency
range....

Yes, i've seen this but (I doesn't read French with ease so) I lack the
proper
understanding of it....But wouldn't the sole purpose with a line loading
the back of diaphragm be to lower still the Q-value of the main resonnant
frequency of driver? Wouldn't this then just result in a somewhat reduced
sensitivity, and a bandwith somewhat extended downwards?
( I've been thinking alittle on this: If the driver was given a phase-plug
on the back-side of diaphragm,- with same slot-area as the front....Then
the
back-radiation could be loaded by a line that might be the "missing
start of the horn itself,- develloped "backwards" from back-throat area
to zero area. But i cant picture if it would be useful for anything....

Source: Sound Digest Archive v02.n716
Hey Chris,
Thanks for the info on the 550 Hz resonance peak for the TAD on a 300 Hz
round horn. I was trying to figure out why folks were getting horns that low
given their recommended 800 Hz crossover point. Also, Bruce Edgar indicated
to me that the tractrix curve doesn't "turn-on" until 150 - 200Hz above its
cutoff frequency. My conclusion is the two factors combine to provide a flat
response to 330Hz; make sense?
While you are saving for those TAD 2001 (I just got a pair... and now I
am saving for the round horns; BTW are you using horns from John / Indiana?)
I have heard that the pre-1990 drivers have lighter beryllium diaphragms
resulting in better HF response. I "think" the pre-1990 are identifiable by
a tan colored cement whereas the post-1990 use a gray translucent cement.
I would be grateful for any other coments/observation/sources regarding
the TAD 2001 and round tractrix horns or on the use of an Altec 515-8G in a
round tractrix / reflex port combo for bottom end. .. the sooner I get this
speaker-thing settled the sooner I can get back to soldering-n-'sperimentin!
TIA

Hello,
Here in France there at lest 1 hundred audio nuts using TAD2001 on the Sato
horn (a 100 Hz acoustical cut-off horn, WE type) , the Tad is electrically
cut above 200Hz (and used from 200Hz to 1000 or 1200 Hz).
But to use the TAD TD2001 at such low frequencies, the rear cavity is
enlarged (I sent a graph about that modification some time ago on Joenet, I
don't have it on that computer so cannot send it at the moment.)
One consequence of the enlarging of the rear cavity is the displacement of
the resonnance frequency (as you know the impedance curve of any loudspeaker
is highly dependant on the rear load, it is the same with a compression
driver).
Some persons like Iwata san in Japan used to load the rear of the comprssion
driver with a long tube tuned in order to annul some reactive part of the
driver when load by the horn, but this has also an effect on the impedance
curve of the driver itself.
Best regards,
Jean-Michel Le Cleac'h, Paris, France

Well, guys & gals, remember about a year ago when I got some surplus TAD
2001's from Disney, and I told you I would post you if I located some more?
Found more of these used Disney TAD's at $150 each. If there is enough
interest, Nick and I will go inspect the lot next Monday or Tuesday.
Interested? Please let me know how many you would buy at $150.00 each, not
including shipping. Drivers would be thoroughly checked out and tested by both
me and Nick McKinney before we plunk our cash down. If we can, Nick and I
plan to purchase in lot quantity to keep price at $150, so we will add drivers
with our order for any Joe who wants one or a pair, or five - for a HT <grin>...
I'll be out of town (going to Georgia on recording assignment) until next
Monday, so I will not be able to reply to list after tonight through Sunday.

TAD (Technical Audio Devices) is a division of Pioneer. The 2001 is
a one inch, 500 - 22K Hz compression driver (which requires a horn). I
think the Disney reference comes from these units having been used at
Disney World in Florida. You can find out more about TAD at:

Retail price is $860 so obtaining one for $150 is a great deal.
This driver is similar to the TAD 4001 (a two inch version) which was
used by Christian Rintelen and R. Luigi Andreoli in the BLUE THUNDER
loudspeaker design featured in Sound Practices Issue 8. The 2001 may
have applications in other high efficiency horn loudspeakers of which I
am unaware.

Hi Raymond,
News is that I have purchased and received the entire lot of TAD's. We
will be starting to test, pack, and ship starting mid to late January.
It is going to be a fun, but lengthy, process. I would hope that many
of the recipients of the TAD's will share experience and advice over the
Joenet when building a system with them.
Nick and I will be putting up pix on the Lambda website soon after I
take the lot of drivers over to his shop.
Yours in music, Paul

SOLD OUT!
Gentlefolk, I had no idea how many of you would want these - I have been
flooded with emails, so please excuse me not being able to post to you
individually. Here is the good news, and the bad news...
The good news is that I have been told by the surplus dealer that there are
"Around sixty of the TAD 2001 drivers." so, I just called him and told him I
would take the entire lot, but only if I could check each driver (inspect VC
for oxidization, inspect beryllium dome for pitting, play music through it...)
He agreed. This will take time.
The bad news is that there are not enough TAD's to go around, and some wanted
more than one pair, for themselves and friends.
Last year, when I bought a total of eight of these, two were blown, and this
lot is in same condition, so there will probably be less than 60 to go around
(I will not be reserving any for me). Each driver will be checked out before I
buy it, and Nick has offered to show me how to run a check on the units in
order to give you a frequency/inductance printout - I don't want anyone to get
a bad driver.
Suggestions on how to resolve supply with demand appreciated! First come first
served? Limit to 1 pair per joenet member? Yikes, an embarrassment of riches...
To answer specific questions:
Shipping would be done through Lambda Acoustics, so I would have to add a fee
in US$ for using his boxes and packing materials. I would let you know how
much total will be depending on where & how shipped.
Payment (DO NOT SEND ANY MONEY YET) would need to be in US$ - check, or money
order, as I am not in retail, so I do not have a bank charge card service in
order to accept credit cards.
All the best,
Paul

I am interested in hearing your opinions about the TAD 4001 vs. TAD 4002.
Are the magnets the only difference? I realize that their sound is horn
dependent, but would like to hear your experiences. What are the basic
sound quality differences? How about useable frequency range, etc. I saw
a pair of 4002's going for $1000.00 in so called "mint condition". Does
this seem reasonable?

Gary,
the 4001 has a slightly different phase plug than the 4002.
when measuring, the 4002 goes a bit higher, but the 4001 has a bit more
midrange energy.
you can hear that:
the 4002 has a bit more resolution, but is a bit cold in sound, and the 4001
sounds
more warm in midrange.
The differences are not that great. just a matter of taste. I know people
actually
disliking the 4002 for its "coldness" (or clarity ?).
With a JBL 2360 horn, the frequency range is 300 Hz to 20 kHz, equalized of
course,
as all constant directivity horns must be eq'ed a bit. The big horn loads the
driver
such that it delivers energy below its free air resonance frequency - same as
in
bass horns, BTW.
Where have you seen the 4002 offered ?
regards,
Hartmut

TAD 4002 compression drivers, very nice condition. They can be used in
either a
1.5" or 2" horn. I'm looking to get $1200.00 for the pair, these drivers sound
fantastic!
I'm looking for a pair of 2001's in working condition to use with my
4001's as
tweeters.
Please email if your interested in buying the 4002's, have 2001's for
sale, or
best of all looking to trade up to the 4" 4002's.
Thanks

Hi all
Interestingly enough, there is one manufacturer who does.
A new horn loaded speaker (called Renaissance) from Hales design group uses
a JBL woofer. The tweet brand slips my mind, but I was speaking with Paul a
while back about custom building a pair for a wealthy client (I *used* to be
in the biz, but not no more...) of mine, and suggested adding a pair of TADs
as supertweets. We never did it 'cause the client ended up with a Meridian
system. Paul said it would take a while to work out the math and prototype
them (he was also going to tailor the throat for the listening room, If we
wanted). They are huge and unusual looking (4'h x 2'w x 4'd(!)) but sounded
spectacular. He was working on a full "cinema" package that clocked out at
$25,000. A stereo pair goes for $15,000. The last time I was at the website,
they weren't up, but might be now. If yer interested check out...

With gladness to be out from under the high end madness,
Chris

Where is the cheapest place to purchase new or used TAD drivers. I am most
interested in the 2001 and 4001.
Has anyone listened and compared the Edgarhorns with 2001 vs. 4001 drivers?
I just listened to a setup in Atlanta using the 2001 drivers and I was
very impressed. It was one of the few systems I have heard which had
uncolored and dynamic sound! I am a little concerned about the use of a 4
way setup, although the sound from this system was seamless and awesome.
For those who are not familiar with Edgar's 4 way, it has a FANE ST5022
tweeter, round tractrix wood mid range (w/ TAD 2001), a straight horn mid
bass with an electrovoice EV15L driver, and the 35 Hz refrigerator. I
think the crossover freqs are: 100 Hz, 600 Hz, and ~10 kHz. Thanks

Gary,
You might talk with John Wolff at Classic Audio Reproduction (810.229.5191)
He uses TAD drivers in his T-1 and T-3 Project speakers, as well as his
Hartsfield Repros. I will be up there this weekend for a listen to the
T-3s. These are 2- or 3-ways (your choice) that use the TAD 1600 series
woofer, TD4001 mid/tweet and, if you and your banker so desire, the EH 703
slot tweeter on top. They are not an all-horn design like the Edgar Horns
(actually, they appear somewhat like his newest creation, but for far less
$$$). The woofer enclosure is ported, the TD4001 uses the TH4001 horn, and
the EH 703 is acoustic suspension (I think).
I have tried several times at the TAD website to get them to tell me who my
nearest dealer would be with no result
Hope this helps.
Regards,
Phil Sieg

Thanks for your input. I plan on building up a system very soon. I am
definitely impressed by the Edgar mid range horn. I have a few questions
about your current system:
> I use no tweet and have them mounted on exempler bass horns >to 40hz. I have
How did you obtain the exempler bass horns? I was thinking they would be a
good match for the Edgar midrange. What drivers are you using in the
exempler?

I am not familiar with the A5 system. Which one is this?

I assume you mean the altec stuff not the Edgar/Exempler setup?

To quote from TAD's website:
"The ET-703 is a compression horn super high-frequency loudspeaker designed for
a wide frequency range and high input power." and "This makes the driver
especially suitable for monitoring digital sound."
sic! Or should I say sick! ;-)
BTW the ET 703 has 107 dB/W/m. Pretty loud... More abouit the ET 703:

Hello,
Also, a lot of people prefer the TAD TD2001 used as a tweeter that means
loaded with a very short horn (calculated for a 3000Hz or 2000Hz low
cut-off frequency) to the expensive ET703.
I used to listen to the TD2001 as a tweeter sometimes and to the ET703 1
single time, well, the TD2001 is not so bad as a tweeter. Nothing as good
as my Onken OS5000T tweeter though...
I found the ET703, how to say:somewhat digital!

Date: Tue, 07 Dec 1999 16:12:09 -0500
Source: Sound Digest Archive v02.n356
Howdy Folks,
Please pardon my continuing delay in posting, but due to relocation to a
new office, a delayed studio/listening room construction schedule,
setting up a new office computer (+ audio editing), one grumpy binge &
purge cat, and all the conundrums associated with a small growing
business — and all of the necessary activities which make demands on my
time — I find I am consistently in a state of behind. Phooey. Yes, I'm
woefully behind in my correspondence too.
Ah, Sundays, a time to catch up... <grin>
Well, there was a good reason why I was offered this lot of about 60 TAD
2001's at a good price - naw, make that a *very* good price... they are
being lowballed because they ain't pretty. Ugly ducklings, so to speak.
But remember — Ugly (in this case) is mostly skin deep. And the duck
did grow up to be of pleasing appearance <smile> and voice.
Unlike the last batch of drivers I got from this dealer — six
cosmetically excellent TAD 2001's which had been pulled from inside of
'PA' cabinets from an interior environment (and for allot more $$) —
these units look, well, Used. Click on link below to see a TAD 2001
picture to help visualize following description...
http://www.tad-pioneer.com/pionrweb.nsf/web/TD-2001.htm
On most of the TAD's, there is exterior rust is around the rear metal band
where the rear housing (covering the VC/dome) meets the motor. In the
above picture, this is the light band around the dark motor. This is a
ferrous plate that has some light to heavy rust.
The surplus dealer (Wade McAlister) told me these units came from under
the pavilions at Disney... ummm, folks, that means "permanent tent"
hereabouts — so while not 'out in the weather' they have been exposed to humidity.
However, the good news is, that the Ugly is mostly skin deep, with
exterior oxidization (rust) from very light to some heavy (pitting). I
started in on the inspection by taking fifteen units apart last Tuesday.
Removed the rear housing, and then carefully removed each VC/dome
assembly.
The interior of 4 of them had humidity intrusion (a poor seal) that was
evidenced by a slight, light brown rust staining (but no pitting) on the
motor plate, only toward the outside edge. On only one driver, there was
some white oxidation on the edge of the beryllium dome, where it meets
the voice coil. The other three of these four beryllium domes and voice
coils were clean.
Eleven of them had no evidence that the seals had problems — in other
words — the beryllium domes and voice coils looked clean. Some looked
extremely clean.
Bottomline: Ugly outside, but inside — where it counts — most were clean.
Some very clean. Of the 15, I picked four to take home and test. Have
just completed a listening test (with a Mapleshade CD) of the four, in
ABCD comparison (to one of the best of the lot rom my previous buy) and
they all sounded (to my ear) the same. Played them full range using no crossover.
My opinion is that the majority of these drivers can be
cosmetically renovated for those of you that wish to do so. Those of you
who have restored rusty iron have a good idea of what I mean.
But, if there are some of you that wish to change your mind about
committing to this order, simply return email me ONE LINE please, and type
in "cancel" or words to that effect WITHOUT quoting this text. I have
54 pages of text to go through to edit the buy list in order to give me
the "first come first served" sequence.
The TAD Plan:
I will pick up 56 TAD drivers from Wade's warehouse tomorrow, Wed Dec 8.
All drivers will be fully tested under load. All drivers will then be
tested for impedance with a printout included, courtesy of Nick
McKinney, Lambda Acoustics, who will be teaching me how to use Liberty
Audio Suite. Our goal is to match pairs as close as
possible to the impedance plot.
Cost per driver will be $150 each to Joenetters only. Prepaid only. SEND
NO MONEY at this time. Shipping will be extra. Shipping will be done
through Lambda Acoustics. I do not have a merchant number, so I do not take
credit cards.
All drivers will be inspected, tested and measured, but as I have
mentioned in previous posts, this will take time. Although I will start
in January with this project, it will take several more months to
complete, so please, be patient.
Guarantees: None. Sorry, not at this price. In the pro sound industry,
compression domes are just not warranted against failure due to burnout
from overdriving. However, in the spirit of Joenetters everywhere, I
will refund purchase price (not including shipping charges) if you are
not happy with the unit, but only if the unit is received in the same
condition as when shipped. This means that if the VC is blown or the
beryllium dome is cracked, the return for refund offer is void.
OPTION from Lambda Acoustics: There are a small number of motors that I
will be selling to Nick that have had the VC/beryllium dome assembly
removed. So Nick is offering the following: He will install a new
(factory replacement) TAD beryllium diaphragm assembly into these motors
for $450.00 total. This price includes the motor. This is half the price
of a new 2001. While supplies last. (The retail price for just the new
beryllium diaphragm is $440.00) Nick is working out a warranty and will
have the details soon. He also accepts credit cards. Nick is also
exploring the possibility of becoming a TAD dealer. If you're
interested, please contact Nick at above cc email address.
I will be getting some pictures of these units up on Nicks' webpage
after the Christmas holidays, so you will have a better idea of what
these units look like.
Some have asked, why am I going to all this effort? A combination of
reasons. About a year and a half ago, I was introduced to the consummate
quality of music reproduction via SE amplification and the Joenet. You
folks (Thanks Rick, Jeremy, Allen, Jeff, Hiroshi, Greg, Larry, and many,
many more ) have been instrumental in helping me to learn to improve the
quality and enjoyment of music reproduction. And I am only just starting
on this big adventure. <big SE grin> This is my way of thanking you.
Yours in Music, Paul

Hello,
IMHO better to load the TAD TD2001 by a horn (or a long tube) to do that
test!
But most probably you yet planned to do so.

Hi Jean-Michel,
Yes, we do plan to horn load the 2001's for testing. However, we have
not decided which horn to use for the tests. The only two we have
available at the moment are a JBL 2307 and a Renkus-Heinz.
Suggestions?

Subject: [JN] TAD Update
Date: Sun, 04 Jun 2000 12:05:15 -0700
Source: Sound Digest Archive v02.n564
Hi All,
Some might recall that I made reference to having obtained a pair of TAD
TD-2001 drivers and TAD 1601b 15 inch woofers several weeks back. I had
not received them at that time, but of course, have since and have
played about with them a bit, so thought I would report my initial
impressions in case anyone might have an interest.
The drivers came with JBL 2307 round, exponential, 1,200 Hz horns and
heavy-duty, 1,000 Hz, 12 dB/octave low-pass, 18 dB/octave high-pass
crossovers, and EV 806A bass modules which contained EVM-12L woofers. I
didn't care for the EV woofers for general purpose woofer use, so traded
them to someone with Edgar Horns, in which they reportedly worked quite
well. In the 4 cu ft ducted, bass reflex enclosures the old 12"
Norelcos would walk all over the 12Ls with a much more lively midrange
and much deeper, cleaner, more pleasing bass response as well as a bit
more efficiency; they made the 12Ls sound bad, dull, lifeless. I would
not recommend the EVM-12L for anything other than for the Edgar horns.
I say that without having heard the Edgar horns, only on hearsay.
I haven't built enclosures for the 1601Bs, but had a quickie listen,
unbaffled. They sounded pretty much like most typical high-power PA
woofers, but, of course, final judgement must be reserved until they are
properly baffled.
I had several 800 Hz horns, in addition to the 2307s which came with
the speakers. I didn't care much for the 2307s, but only tried them
with the 1,000 Hz crossovers. I later found that I didn't like anything
with those crossovers. I tried the TD-2001s with the Emilar bow-tie
horns. Didn't like them either, too harsh sounding. Also with a single
800 Hz Emilar horn of more conventional design. OK, but still not up to
expectations. The 800 Hz tar-filled multicellulars were the clear
winners. But, I found that I really didn't care for them either when
used with the crossovers that came with the speakers. In fact, the
full-range Norelcos sounded better alone than with the TD-2001s and the
tar-filled multicellulars when used with those crossovers. A simple
series cap and resistor sounded MUCH better.
I sold the 2307 horns to a chap who used them with simple cap crossovers
and JBL drivers, and thought they sounded quite marvelous. I did not
try them with the simple cap crossover though. Oh well.
So, I am temporarily running the TD-2001s on the multicellulars atop the
12" Norelcos with the simple, temprorary high-pass crossovers with the
Norelcos running full range. I don't seem to sense that there is much
need for a more complex crossover, but I will get around to biamping
them one of these days and/or perhaps winding some inductors to roll off
the Norelcos. Since the Norelcos are positioned down rather close to
the floor, the high frequencies bounce about the room and don't seem to
be all that objectionable. Hopefully, proper crossovers will effect an
overall improvement.
The TD2001s on the 800 Hz tar-filled multicellulars do seem to sound
quite nice, very musical and full-bodied with no trace of harshness,
rather, a balanced and pleasing sound without any annoying high
frequency edginess or roughness. Once I get a proper crossover
implemented, hopefully, they will sound even better.

I hear ya, bro!
I've been listening to a cassette I made in Madison back in 1978 of a Nat
Adderly concert, which I was allowed to make only because I knew the bass
player & drummer. God, if only I had known what I was doing & could have
made a better recording! The playing was great, although the recording
frankly sucked, and I'd never play it for anyone else. But it's like
reading a good book - once you get into it, you don't even notice that
it's only words on a page...
The whole idea, especially in jazz, is the ideas that come through,
right?
Regards,
Ross

hi gordon,
don't have the number or anything, but there was thread on this (globe 300Bs)
on r.a.t. somebody reported that the guy who makes these is his personal

Hi :
I am in Tiawan. The maker Tel # is 011-886-2-27012840 (Asian Time 11
AM~9PM). Address
No. 192-1, section 2, Fu-hsing South.
Taipei City
Taiwan.
Will disclose the fax # when I find it. The asking price for 205D is NT$6500
(almost $200/ea).
I believe most of the tubes are made in mainland China (quality is so so).
So, think about it if you want to buy.
Regards
stanley

Hi Folks,
Has anyone done a comparison, or would like to offer an opinion as to
which is best (assuming that I can hear the difference! :-) )
I'm thinking of the 20:1 50 mA SJS line output model pa107 vs. the Tamura
model F2007. These two are roughly the same price.
Does anyone have any experience of the F5002 amorphous core at three times
the price?
It's for my 12B4A based headphone amplifier.

Somebody on the list mentioned that Tango makes a couple of center-tapped
chokes, suitable for plate loading a pair of driver tubes in PP. One was
built with iron and the other permalloy. Anybody know any more about
these? I haven't been able to get any statistics on them. I will be
running 25mA and swinging +/-150V on each side of the choke--vt25's driving
845's -- any chance either of these chokes could handle that?
Thanks once more, John

Hi John,
You might be interested in the following Tangos:
TC 180 12 WN is AFAIK the only one with Permalloy and takes only 12mA/90H
15 mA max.) for your purpose and will set you back for about 17,000 yen, if
memory serves right.
TC 60 35 W takes 35 mA/ 30 H ( 50 mA max.) for your purpose, is a "normal"
cut-core devise and costs 11.500 yen (P&P excluded).
There are also others with lower current and higher inductance or higher
current rate and ( much ) lower inductance.
If you have a serious interest you could fax to Soundshop Big, attn. Mr..
Yokota. He is English literate.
He might send you a datasheet of the item of interest on request
Fax + 81 474 82 3039. No e-mail or website.
Good luck,
Ernst-Jan

Thanks to everyone who was kind enough to send me the specs on Tango chokes
a few weeks back. Unfortunately, I could find no mention of the voltage
swing capabilities. I'm no magnetics expert, but shouldn't that be a
concern for chosing a suitable plate-load choke? Is current the critical
factor here or is voltage times current a better indicator?
Thanks again for all the shared knowledge, John

I've got a pair of these too, and they're nice IF you use the whole

secondary winding (which is necessary with either high primary

Any thoughts on why?

Source: Sound Digest Archive v02.n539
Looking for some advice here. I picked up a pair of dual concentric drivers
and crossovers ad put em in a suitable sized box and "tuned" to a happy port
length.
Difficulty I am having is a upper midrange voice brightness. I have never
say and listened to the studio monitor using these drivers but comparing
them to my Missions they are peaking an octave or two under the crossover
frequency. So high male and female voices are a little bright. Is this a
damping problem or possibly a refraction problem. I realize I am a little
sketchy but I really am not sure what to try next and funding has almost run
out so I need to try to get it right the first time.
I have tried lining the cabinet which incidentaly is 3/4 inch customwood,
substantially glued and screwed, with polyfill and that helped with the
boxiness but didn't help the upper mids...

Hi there,
I have owned Tannoys Silver 15" and of course have run after such plans...
What I got from Tannoys (after much problems) was 2 or 3 different versions
of the GRF, and I mean "totally different". Ranging from a corner horn à la
Klipsch to the actual Westminster...
I've given the plans to the guy I sold the drivers, but I might have a copy
somewhere of one plan. I'll have a look today and let you know "if" I get
something out of my acheologic searches...
I now use the Tannoys "Ardens", wich are 15" with foam surrounds in huge
bass reflex boxes. (I equally have a pair of 12". In my view the more modern
drivers have less peaks and dips in the mids, but have a bass that's less
fast.

Source: Sound Digest Archive v02.n092
Hi All,
I came across a bit of a problem with the Tannoy Golds. The chap who
bought them found that one is somewhat brighter than the other. I
hadn't noticed this in 30 years. Oh well, so much for my golden ears.
Anyway he measured the VC dc resistance and found the brighter sounding
one to measure 11.2 ohms, 0.88 mH and the other 12.1 ohms, 1.19 mH. The
Tannoy bloke says they changed to a lower impedance back around that
time and it sounds like I may have one of each type which he identified
as a 3LZ and a pre 1970 diaphram. Further, he added that the part
number I need is 7900 0205. Not to definitive an answer, all in all.
He suggested that I call the North American Distributor to order the
part.
Well, they exactly didn't come of as experts. The first person said
that eleven ohms sounds about right and referred me to his in-house
expert who didn't have a clue. While on the phone he went over and
measured one and reported that it measured 9 ohms and that part number
was the only diaphram they stock for the 12 inch Gold. So this all
totals up to about zero as a solution, as I don't intend to buy two
diaphrams at their prices in order to get a matched pair.
Anyway, if anyone has any experience in this area and can offer any
helpful information it would be much appreciated. And if anyone has a
pair of 12 Golds handy, I would appreciate it if you would measure the
HF VCs and email the results. With a bit of luck someone may have the
same problem and we can do a trade, or something, or perhaps someone has
a new or used replacement diaphram that will match one of the exisiting
units which they would be willing to sell or trade. Stranger things
have happened and you never know until you ask.

Dont know about "Little Reds" but i have info on Tannoy Reds as used in
recording studios.
These use a 15 inch dual concentric driver and adjustable xover VERY similar
to those used in previous Hi-Fi models. They are higher powered and slightly
less efficient 92db. Box is a moderate sized bass reflex and sound flat to
bit less than 40Hz. Would go below 30Hz if box bigger.
They will go VERY loud as can take peaks on 500watts below 1,000Hz and
250watts above.
Would be OK as Hi-Fi speakers too.
The dual concentric works as all you Tannoy owners know and offers a certain
sound coherence not found with multiple separate drivers or large panels.
Maybe Little Reds are a smaller lower powered version with a similar but 12
inch or 10 inch driver.
Cheers,
Bart

Anthony, there's a guy in our area who used to work with Vu (of "Deja Vu"

Hi All,
I recently picked up a one-only 12" Tannoy Dual-Concentric stage monitor
speaker and would like to find a mate for it, if anyone knows of one.
Anyone ever play around with these or compare them with regular
Tannoys? It looks to be a relatively recent model with a gold frame and
a ceramic magnet. A black plastic dome covers the tweeter diaphragm
and it has a fabric cone surround. There is no model number on the
speaker or the enclosure. A raw speaker would be of interest as well,
or if anyone has a pair of Tannoys and is keenly interested in an
excellent stage monitor, a trade would be gladly entertained (yeah
right) - with boot, of course. A pair currently listed on eBay is
identical in appearance, for identification purposes, in case anyone
needs to ID one. No, he doesn't want to entertain a trade.
The speaker in the stage monitor differs somewhat from Tannoy Hi-Fi
versions in that it is designed for high power usage with a quite stiff
cone suspension resulting in a rather high fs of around a hundred Hz
which makes the bass resonse a bit thin requiring a subwoofer. Aha, a
perfect excuse to get on with the enclosure for the 18" JBL 2245H, come
spring. Anyway, except for the lack of low bass, it sounds quite nice,
better than the speakers I am currently using. I'm getting tired of
screwing around with trying every darn speaker that comes along and
would like to settle down on a more or less permanent system and a pair
of these with the big JBL sub driven by a SS amp and the JBL BX63
xover/eq would keep me happy for a good while.
A pair of the 15" JBL 2235Hs in some sort of trade for the 18" 2245H
would be of interest as well, as they could be used in my current
enclosures.

Hi All. Here is what I got from Tannoy technical support.
Hi David
The 12" Monitor Gold (LSU/HF/12-8) was the successor to the Monitor
Red which succeeded the Monitor Black. The improvements were 8 ohm
impedance instead of 15, slightly heavier cone mass for better bass
and a higher power handling capability.
To get 40Hz from these units you need a cabinet of about 150 litres.
No plans are available for this size but you can make a cabinet from
25mm Finnish birch plywood using standard speaker principles. There
are many books and articles about how to do this. Tune the cabinet to
35Hz, I suggest 2 port tubes of around 100mm diameter and
200mm long to start with. Extending the tubes lowers the tuning,
again there are standard formulae for this but to do it accurately you
need to measure the impedance in the 20Hz to 100 Hz area using a
sinewave oscillator and an analogue multimeter and tune the dip
between 2 peaks to the cutoff frequency you require.
This is what I built, with the exception of using a single 150mm port.
They are lovely sounding and I will keep them for a long long time.
Regards, David

I don't know which Tannoys you have. I have Tannoy 15" dual concentrics
Monitor Gold (current from '67-74ish). I considered the Tannoy horns, got
the plans and decided that were too hard to make. I asked Tannoy for their
recommendation for the best simple box. They said a 300L box with four
ports all of 100mm diameter, 250mm length. I did this and am very happy
with the results. Very important in a box this size (about a domestic
refrigerator size and shape) is to brace and damp the panels well. Mine are
50mm thick with sand inside the walls. I could look up Tannoy's
recommendation for the 12" Monitor Golds. They had a smaller suggestion
also. I suspect that sealed would not work. I have heard my drivers in a
smaller sealed box and there is just not enough bass, a consequence of the
low Q. My boxes with reflex loading and using their proximity to corners
measured flat down to 20Hz although T/S sums would have suggested mid-30s.

>Hi Martin,
Actually, I'm Peter. I thought of the martincampbell email address as my
wife surname and mine together. Now people address me as Martin. Anyway, to
the topic at hand:
>
> I forgot to add that I was thinking of a subwoofer complement. How

>with?
The 15" are somewherre about 96db/w/m. To put it another way, on the same
volume position they sounded equally loud as the Lowther PM6A Acousta they
replaced and much louder than most other speakers that I fix up for friends
etc. IE the usual 87-90db/w/m sort.
I guess the 12" and 10" might be a couple of db less but I have never heard
or seen those.
I am using a single-ended VV32 amp of my own design. These have curves
almost exactly the same as a 300B and I use them at an operating point that
should in theory give about 12W. This is plenty of power for the tannoys.
Many people think SE amps are not up to providing the bottom octave. I
think this is only true if the output transformer doesn't quite have enough
inductance and this unfortunately seemed to me to be the case for quite a
few well regarded trannies when I was looking at specs and trying to get a
synthesis of people's subjective impressions before buying a transformer. I
am using a Sowter SE08As which have a pretty beefy 6Kg core.
Most people comment favourably about the deep bass of my speakers. It
happily reproduces the low rumbles of trains and trucks etc that make their
way onto certain recordings. Organ pedals can get that nice "shake in the
air" effect. With test tones in the bottom octave I can make the room's
plaster board walls vibrate. When an acquaintance put a microphone in the
port, the output looked flat from 20Hz to 70Hz although I know it is
supposed to just be a hump for only a third of an octave or so. The box is
tuned to 32 or 35Hz from memory, the free air resonance of the driver is
supposed to be 20Hz. I am deliberately using proximity to the corner to
help the bottom octave.
In summary I don't feel the need for a subwoofer.
I have the reflex box suggestions for the 12 and 15" Monitor Golds from
Tannoy.

Dear Joes,
Looking at the UREI809 reminds me that I'd like to know the
correct calculation method of tapped inductors.
Would it be like this ? :
A-coil-B-coil-C
L(A-C)=square ( sqrt(L(A-B)) + sqrt(L(B-C)) )

Have you seen Walt Jung's section on that in AD's System

There have been some posts on this recently.
As an avid FM listener I do need to record and time-shift broadcasts that are on
at inconvenient times.
I used to use my first HIFI VHS VCR for this but it died and the one in the tv
room now has no record level controls Just ARC. most new models don't anymore.
So I've been looking for a S/H replacement. First one I took was a Philips,
terrible, but they let me swap it for a National / Panasonic model F55, which
has 4 heads and VHS HQ. My guru now tells me that it's one of the last of the
good ones, along with the F90 and the Sony's. Solid chassis and transport,
only design flaw is a regulator that runs too hot and needs a heatsink! It cost
me $aus 205!
It sounds wonderful, despite not having the sheer hobbyist cred of a big 10.5
inch reel Technics 1500 or a Revox. I will be making comparisons with my
Nakamichi BX300 (set up fo TDK AR and Dolby C) tomorrow night. Next project is
to make some 'party' and 'dinner' tapes.
I wonder if anyone else has done this, one advantage is being able to set the
timings on the machine instead of on a mains switch timer. This is I think a
serious option for the cash starved audiophile. Despite the less than good tape
handling. I wonder where I can find a Sony ADC and DAC thingies? The PCMF1 and
701 ring a bell.
It is crucial to switch them to Aux/
