The AudioFederation guy posted pictures from RMAF show with Cogent room. (The images are courtesy to http://www.audiofederation.com)
I was wrong in my previous post, as Cogent did demonstrate their loudspeakers with Ionovac ion tweeter. Yester...

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...

I do not know the characteristics of the Cogent bass driver. I do not like the entire idea of a bass driver be electromagnetic as bass defeat itself first with field coils, still if electromagnets is something that Cogent intend to do then they are w...

Another Rocky Mountain Audio Show went on and Cogent dragged this filed-coiled asses :-) to the show. I was wondering is any changes with Cogent during the last year took place. The unfortunately-famous whore : Jonathan Weiss - has become ...

[quote user="Paul S"]I recieved and accepted an invitation to hear an earlier version of the Cogent speakers, and I was subsequently asked for a considered opinion of the sound. I guess the designers had read from my posts various criticis...

It looks like the Cogent boys came up with a new design. It is good that they are keep looking, even thogh they unfortunately are restricted with their desire to stretch the use of their drivers over too wide bandwidth….

Paull, the horns might be “beautiful” but only themselves. When they are jointed with the rest Macondo spherical chennals then I do not like how it all looks together. Regarding the drivers, I do have a few options, I might slowly exercise them and ...

[quote user="jweiss"] When we spoke at CES, you mentioned that your experience with field coil drivers only extended to cone types. So I assume that you have never heard any field coil compression drivers. That would include the WE 555, 594, RCA 1428...

Hi all
The first link, to the musique_concrete website was because there's
pictures of some horns made for the S2 .
I hope anyone interested in JMLC horns read the last four links,
where Jean-Michell writes about his reasoning for his horn ...

It only uses Cogent f.c drivers .Josh Stipich from Electronluv is the designer/maker of horns and amplifiers and Cogent role is secondary (my guess) . Electronoluv aproach is afected by Sakuma designs and using lots of transformers&nbs...

Well, I have a theory that the rough surface may be helping to attenuate multiple back-forth axial reflections, but from what you say, it may be that it results in - what's the proper term? - irregular as opposed to laminar flow at the surf...

[quote user="clarkjohnsen"] And what they were doing, at CES 2006, was fine indeed. [/quote]
Nope it was not. Cogent sound was not near as interesting as it could/should be, and the Cogent boys know it, or at least they are slowly learning it.&...

The big RCA field coil is the best thing about the Cogent system. It has great "promise", based on what I heard. Although their methods of "developing" this driver seemed confused to me, they do have truly encyclopedic knowledge...

[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="jweiss"] It was good to finally meet you at CES at the Cogent Room. I guess that you really found Steve and Rich's drivers pretty interesting (you initially wanted to buy a pair of the midrange drivers, remember?) [/quote]

My experience is what Romy would call primitive, but I did hear these horns and can only compare them to sound reproduction in general, not other horns. There was a sub as part of the scheme, don't know if it was actually part of the original d...

It was The Rocky Mountain Audio Show a few days back and I LOVE it. The best things about the show that I wasn’t there, thanks, thanks, thanks, God!!!
But it was not actually all. I had even more pleasure today when I went on-line to The AA Sewers ™...

I'ts not that I feel "someone else's would be more informative than Cogent". Rather, even though I know what I heard from the Cogent version, I cannot at this point say I understand how much and what part of what I heard is ...

OK, I split the thread: “Best of the HE2006!!!” there extracting the Cogent’s related posts into a separate thread….
