[quote user="cv"] Well, the Cogent (Steve Schell and Rich Drysdale) boys are building just such a beast: field coil magnet, (possible) permendur polepieces for >2T, Fs 70Hz, throat - dunno, but at least 3" dia, reduced compression ratio relative t...

[quote user=" browellm from hifiwigwam"] "not your typical DIY moron". High praise indeed from Romy there… [/quote]
OK, I would like to make a commentary on the subject. I know that people who love to chop wood at DIYAudio site would consider...

I have not made any measurements on these drivers, I've just heard.
at 100 volts the sound is similar to the original Alnico magnet, at 130 volts instead of the original seems to be more shr...

I wrote a few weeks ago a typically-pissed article about hypocrisy and lie in audio and how you, the fools, allow it exists in audio, despite that we would hardly permit it to exist in our “out of audio live”. I did not posted this article yet but an...

[quote user="twogoodears"]I'm following with interest the thread and must say that I'm baffled: Goto's "instructions" are - SIMPLY said - a mix between non-existent and wrong... I love what Goto's did in my system... BUT I think I did more with "...

[quote user="oxric"]Mike duly explained to me that he would not vouch for the work of anyone not qualified and experienced with Vitavox drivers, given both the complexity of the work and the number of parts that go into making these drivers. I as...

[quote user="jessie.dazzle"]However, I must say, I have a lot of trouble accepting the idea of redundant drivers. [/quote]
Yes, it dose not sound attractive to me but it is not the redundant drivers but one main driver and another at minus 9dB drive...

Hi Romy,
FYI: The previous photo of some unknown persons "pile o' horns" appears to be:
Upper midrange: 1" TAD TD-2002 mounted to 650Hz Edgarhorn
Supertweeter: Fostex T90A or T925A.
Lower midrange: ...

[quote user="haralanov"] For some unknown reasons, he later decided to change it with the sharp and artificial sounding fostex supertweeter. What might be his motivation? Logically appears the following question – is that Goto supertweeter so hor...

It looks like a new horn maker wanted to be know: the Eleven Horns

[quote user="RonyWeissman"] The HF sound is very quick and weighty , which can be quite nice on classical guitar for examlpe, but the tone is not clear enough, meaning for example cymbal attacks don't have enough metallic ring to them, nor enough blo...

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...

In my current scenario I
have slightly under 11 feet between the MF driver diaphragms. The optimum listening
distance in my view somewhere between 8.5 and 10 feet with the acoustic center
line pointed to shoulders. This is my typical configuration...

We are closing our new house in 2 weeks and while packing
and preparing to move I am thinking about the configuration of my new playback installation.

[quote user="Romy the Cat"]So, if the Ultimate MF Compression Driver is used from 1000-1500Hz then why shall it be able to play 500Hz? The answer is: he harmonic reserve – the driver that will be suited for 500Hz will have larger cone and softer sust...

That was a subject of long consideration for me and I ruled
not to go for time alignment. You see, my current listening
position is 8.5 feet from the diaphragms and my ceiling height is 14 foot. Let pretend
that I am siting at 4 feet at my listeni...

user="rowuk"] I certainly understand how someone would like to have

the room through variable dispersion could very much improve the relation of
articulation to t...

Yes, this English pace did not give a lot of new information. I know nothing about the AudioTekne Company. I like that they wrote about their bass driver but I do not know how much truth and the actual results behind it. I do think that they wor...

The first level of listening perception is Static Level. At this level a listener perceives musical information as a collection of the individual sounds and a listening awareness tries to evaluate the “convince-ability” of those sounds. At this level...

[quote user="Romy the Cat"]Sean, this subject is tricky. You might like your original Altec 802 better than your new 802G. (I did not

Electronluv,
I decided do not spoil the “Who built horn” thread what juts was an announcement of availability of different horn boulders. I also did not want to continue the following thread:

thanks I have a few questions to ask if you do not mind:
1) Did you experiment with surface of the horns and a negative contribution of smooth surface to Sound?Smooth surface are fine don't waste my time on a trival matters.
