Zu Audio treats their drivers (from Eminence) in various ways, not sure if they dip them in liquids, but I would not be surprised. You've heard them so can judge their Tonal results yourself....

Anybody who ever tried SS amp with compressions drivers or the drivers of high-sensitivity that can be driven by minimum current knows how it works. Nelson Pass created with his First Watt project a lot of publicity to the idea. A few watts, in p...

I was trying the drivers in my infinite baffle parody configuration and I have to admit that that all of them sounded not good. There is not even a fraction of tone that am loosing and from any other quantifiable subjective point of view the driver d...

audiofilofine, I do not like when they just remove the magnet and to replace it with electromagnet coil. I do feel that in this configuration the coil is not vented well and either the driver has too much thermal stress or it will run only at very lo...

Hey I read around here of the importance of time aligning drivers, and am trying to build it into my horn frame, but I'm starting to wonder, if tweeter frequency wavelengths are around and inch long, wont I completely loose any alignment if I sit hal...

Hi Roman, hi all... intriguing post and interesting questions, as I've been for about 20 years a triode and, before, a tube user and a glowing-in-the-dark maniac.My experience...I purchased - years ago - an Hiraga 20W which I used as a bass enclosure...

This is something I have been at for the last few years, I have tried a few drivers, at the moment some of my favorite are the vintage RCA MI 1443, yes filed coil and some funny cone diaphragm, they are used from 500 hz to 5 khz with a Fostex T...

[quote user="Merlin"]Romy,
if you see my post you will notice that I mentioned I did not know of any drive units that could successfully be employed. Can you list some?
Here is a typical high quality 15" cone - indeed one of the finest on the mar...

Movingcoilguy,
sorry I know nothing about the Wharfedale drivers, speakers, nether about the Goodman cabinets. Mau-designed boxes are also very much not my area of expertise. In fact, if you read me than you know that I have a strong attitude again...

[quote user="Wojtek"]Funny , I visited a guy who ususally picks up audio stuff from the curb (garbage picking) and noticed some 4 small Mission midbass woofers with crossovers. He said cab wasn't worth to save . What are the serial/ type number...

I have also used the Eton drivers in a MTM configuration and I very much enjoyed the sound I was able to get out of these for several years until I got the EdgarHorn speakers. Actually, I still have the dynamic speakers set up in the same room, very...

[quote user="cv"]I make 6 drivers = 95.8 db/W. You get 3db / doubling of the number of drivers ie 88 + 10log10(6 drivers).That's why I'm going with a bunch of Lambda TD15S (which are sort of a cross between the Altecs cone - paper, curved, ...

The exceptional 15-inchers would be two fitted in two categories: the bass 15-inchers and wide-range 15-inchers. It is imposable to think about the exceptional and wide -range 15-inchers and do not mention the 1946 -1973 production of the Tannoy Dual...

Oops, I almost forgot the size of 14”. This is kind of off the wall size but still there was two exceptional drivers in this size that I met.
The first is JBL 1400ND. The 1400ND was initially used in JBL K2 system. It had underhung voice coil, neody...

We enter a complicated region as the lower driver we go the drivers could be used for different purposes and it is very hard to generalize. A 10-incher might be MF driver and LF driver. In my past I experimented with few MF 10-inchers, including some...

Thanks for alternate driver idea, Romy. Sounds interesting.I certainly do not need all the gain from the ML2 along with my AI M3A phono/pre-amp, so I will give the 5687 family a try once I figure out a decent, fool proof pin-out adapt...

This is about the Focal Utopia TN51 tweeter....
It is hard to imagine not much I like this tweeter, in fact there is something insanely beautiful in this tweeter and from a certain perspective (narrow-certain) I like it even more then the HF o...

[quote user="oxric"]Romy's comments, not coming from someone who has insider knowledge as to the manufacturing of these drivers, must be taken with a healthy pinch of salt. Why he seems so opposed to these drivers which are not even that expensiv...

[quote user="oxric"] I have always felt that if I went for a vertical array of 10" drivers, I would keep the drivers closer spaced than you do in your 'Dunlavy' made enclosure. Based on the 110" height of the tower, I see that you would be doing this...

I was slowly looking for a compression driver that would go in my Fundamental Chanel down to 200Hz. The YL Acoustic 550N attracted my attention. Then I realized that it is the narrow throat type of the drivers, aka WE555, not exactly that I would...

[quote user="el`Ol"]A $$$ solution for a bass array that comes into my mind are the sandwich cone drivers from Accuton.Monstrous neodymium magnet, underhung voice coil (for low flux modulation).Very low Fs.Relatively low QMS for use in sealed enclosu...

[quote user="de charlus"]Ok, understood, at least somewhat. Are you suggesting that the S2 operates at the frequencies between 1000hz and 3.6khz? I am not insisting upon using the driver at the frequencies that I was initially suggesting; far fro...

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, ...
