It is interesting… complaining about the fact that the “promising to be claver” Cessaro Horn using the TAD drivers (still it is not completely known as they said that that MD driver cost €4000) I asked myself: what else they might use? Really, ...

If you know how in some optical systems imagery get destroyed when an aperture getting closed to F64 or even smaller, then you understand what happens in compression driver when frequency get higher and spaces smaller. Yes, the proximity of wavelengt...

I would like to make a few comments about the entire idea of those expensive Japanese compression drivers: GOTO, ALE and alike. I have voiced the near-similar outlook about the irrational exuberance that some audio people express about electromagnet ...

I would discard the first part of your post. It is it truly irrelevant what Germans, French, Japanese or Brits were buying and what particular brand and in what time they consider as “fashionable”. It is know that Ebay or Akibahara popularity has...

Well, when we are talking about Cogent we need clearly differentiate two things: the Cogent’s drivers and the Cogent’s installation. The problem is that since Cogent’s drivers are something so called “compression drivers” then their performance might...

Well, whatever you do with your loudspeakers of with you whole playback system is kind of irrelevant if your drivers are not right. In my view the drivers are the very much heart of playback but in case of High-Efficiency and particularly horn-loaded...

Why do we use DHT tubes? it is not because of their technical specifications. They have low transconductance, a problematic direct filament, and they cost a lot.Obviously, it is because of their sound. Some people like it and some people don't.The DH...

[quote user="Jeffrey Jackson"] first, basshorns... the basshorns that I posted here some years back are my straight ~50Hz horns (my memory is fading)... they are 8' long... then rear chamber.. mouth ~ 3' x 4'... throat ~8" x 8"... rear chambers of va...

[quote user="be"]The best driver I have heard is the TAD 4003.
It does not use the secondary resonance of the suspension, as described by Duke LeJeune above for the TAD 4001-4002, to extend the response towards 20 kHz, but has a natural roll off fro...

I still remember proposed solution for symetrical TAD 1201 horn loaded midbass sections. Was it to free listener from sweet spot low seat position ? I could imagine that that midbass horn performing up to 1000Hz sitting low on the floor would impair&...

[quote user="coops"]…. Avantgarde charge how much for their large Trios yet the modified conventional drivers they use cost only a few bucks each… [/quote]
Avantgarde Trios were $38K retail, overprized but still conventional in the world where the M...

Oliver,
Yes, in the first links that you sent it is clearly visible a fabric suspension – very interesting. Who is that guys? Are his drivers commercially available? Well, I asked and then I made a pose for myself. Well, a hard-suspended and fabric-...

Hey Romy,The Goto drivers (505TT, 100-8khz) and horns (S150, 150hz round exponential) finally arrived. I've only had them for a week so I can't say much about them besides they're not a simple drop in replacement of the previous 10" TAD woofer (200hz...

I seem to remember that we've covered somewhere the sonic benefits of SET at lower frequencies, but I guess I never really thought of ULF as "bass", per se. If someone ever comes up with an SET that can be an effective part of an AuraSound circuit, ...

Antonio,
The drivers are Seas Excel:

"The SEAS Excel woofer Line offers 2 proprietary cone materials, available in drivers sized from 12 cm to 26 cm. SEAS ...

[quote user="Paul S"]All I want is wide-range drivers as fast as a Lowther DX4 [/quote]Paul,
I have listened DX4 driver. In my view
this fastness that you report is completely artificial and absolutely non-musical
as it does not have any relation...

By the time I got seriously involved in hi-fi, in the early 60s, speakers and their drivers were already undergoing significant changes from which they would never "recover". Basically, for reasons that are no longer clear to me now, drivers and...

[quote user="Romy the Cat"]Here is the idea that I had for the “ultimate bass” for my room. Below is the picture of Macondo one channel as it is now from my listening position. So, if I find a way to deal with the wall edge at my ceiling then I migh...

Hey, Guys, I have a question to ask. Are any in existence 10" paper-cone drivers with free air resonant frequency around 20Hz and sensitivity over 95dB-96dB? The caT ...

Hello again,I've found four Scan-Speak 25w/8565-01 and possibly two -00 for sale at a good price.I'm triamping as of today and hope it's a good idea to start with the four and perhaps add more when I can afford it.- Do you think the 01 version would ...

Hi Cat,The more and more I listen to reproduced music, the more I realize dynamics and tonal respect are key to start any reasonable installation. This kind of crosses over into some driver discussions so bear with me...My Tannoy 10" ...

The Aura
1808 had free air resonance at 24Hz and required enormous sealed
enclosure of 14-16 cu feet. Wilson Audio used the Aura 1808 in their
unfortunately-ported XS subwoofers and soaked from their relatively
small enclosure an extra 19dB...

I have had similar impressions to other speakers using these drivers. For example I found the top of the line Avalon Eidolon diamond to be similarly colorless and lifeless. Also a pair of Vaic speakers (designed by the guy from Lumenwhite...

Thanks for the link, el`Ol. The original Görlichs, when they still use aluminum layers were very interesting, thought they were soft suspended drivers that is not my cap of tea. BTW, for whatever it worth the Magico new version does not use ADT...

I just found this thread and can comment on the Enabled DX4s. Limono (Wojtek) very gratiously loaned his Enabled 8 ohm Lowther DX4 drivers to me this past summer (summer of 2008). It took my a while to make the crossover for these (I have...

It may be good, though i've worried about SS since Tymphany took over. I have seen many good companies with good products completely screwed by new management. Their re-packageing of Peerless into V-Line (or whatever the hell that was) sp...

Try thinking about it like this: Moving your ears 1/2" closer to all drivers in the system is not the same as moving a single driver 1/2" closer to your ears.jd*...

I think clearing this up this may be of benefit to other users who are building multi-way horns.
Let's say I've got two horns mounted on a frame. There's a high horn
above and a mid horn below and they are physically time aligned, meaning

Romy:I think you may find the link and the shoot-out, of limited value as they are, of interest. The S2 did not fare well at all, not surprising really, given its idiosyncrasies and how difficult it is to get anything remotely acceptable out of it. h...
