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...

[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.&...

Were is the big red horn pic with the cogent drivers on it?thanks josh...
|
Thank you for giving this matter your attention. Jorge, I was intending that the AK151 be employed within a horn. Further, once I had settled upon the driver compliment, it was my intention to retain the services of Jeffrey Jackson, since I am not su...

Hi Romy,
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?) It would seem from all the activi...

Part 5: HornsIt was quite bad, bad on all horns…..
The first was the “new horns guy” …
(references to: http://www.goodsoundclub.com/TreeItem.aspx?PostID=484)
This year behaved quite nicely. Seeing me he immediately told that he has not...

Romy, that horn is so beautiful that I almost do not care about how it sounds! I actually hopped on the thread in response to the header advertising the desire for 450 Hz. and only after that did I read the Oswald's Mill stuff. In pasting the link ...

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 ™...

Hi Paul,The Cogent diaphragm I have seen pictures of was woven carbon fiber with a leather outer surround. I have never listened to a Cogent 1428 but they must sound very good, at least Bill Woods and Bruce Edgar say so.Besides their overall ultra cl...

[quote user="cv"]Little suggestion should all else fail - you could have a rudimentary phase plug machined that would give you the same (or similar) compression ratio as the original but only one annular exit path. This might preserve the driver char...

What the sonic impact will be? I clearly have no idea. I was slightly desponded and warned that my excremental S2 with electromagnet did not have the “sonic impact” that I find useful.Regardong the Quartopuss... Chris, you're confused because t...

Hello Guy,Please excuse the rapid fire response, bit short of time today.1)Your comments about the Io cart are most interesting; clearly it ain't about saturation. Here's another idea: if the domains in the magnetic material limit resolution (leading...
|
You are correct about misuse of the SETs in my experience, I suppose, because I have only started with an SET amp as a pivot on one occasion, but then I wound up loving the speakers more than the amp that couldn't drive them. But I have he...
|
[quote user="Wojtek"]This is probably the reason I can listen to EV Patrician IV in relatively small space and close to the speaker without much of fatigue. The other factor must be that it's 4- way design with narrow band-pass for each horn. E...
|
[quote user="serenechaos"] I'm just looking for any good information on how really good drivers are built; and where to look for if there are problems. As you have evaluated quite a few drivers I thought you (or someone else) might have some su...

[quote user="cv"] Or build your own outer magnetic circuit as you are saying, retaining the S2 diaphragm, phase plug, pole pieces and throat.... [/quote]
If you read the thread form beginning then you will see that it was my original ultimate intent...
|
Which RCA driver you use? RCA had a few drivers the pre and after war. I am familiar with a few after war drivers that I tried in my 330Hz horn and I was not impressed. Reportedly the pre-war MI-1428B shall be the one to play with; I did not have thi...

[quote user="Paul S"] Do you find equal benefits from the same oops levels (and/or placement) with all types of music at all listening levels? [/quote]
I did not detect any fluctuation my “oops” desire with listening levels. The Injection Channel is...
|
I don't know the full story of how loudspeakers went from field coils to permanent magnets. I believe that ultimately it was dictated by the price and availability of Alnico. Eventually Alnico became cheap enough to make similar or higher strength ma...

I had today a conversation with RAAL’s Alex and he pinched to me a very interesting idea. He feels that I attenuate the outpit of my “Water Drop” too much. I have no doubts that I attenuate it as much as necessary and Alex proposed that I do too much...
|
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...
|
Rakesh, yes, this is what upsets me – the fact that I do see a lot of God’s irony in the event and in a way I find it … stimulating. Hey, I do not even believe in “God” but I find it stimulating. Thanks, Gordon. I do (did) have the Bent transformer ...
|
Kerry, thank you for sharing your paper diaphragm idea. Very interesting. As I remember it, the Cogent diaphragm I saw (and listened to) at Steve and Rich's place was a flat disc of something like fiberglass, and it looked relatively heavy for the ap...

The subject it itself is very interesting and although it not directly relates to the Experience Music Horn Installation but there was some talk about in this thread. There was conversation on the similar subject at British hifiwigwam forum

|
The point of the field coil is to saturate the piss out of the magnetic circuit so that the coil flux does not modulate the motor. Romy, I suspect that your experience of them may be based on an older drivers where saturation was not the name of the ...

What your little G.I.P Laboratry does is absolutely irrelevant. They feed already pre-buttered customers and their moves are not important. Shindo and Cogent do the electromagnets for years but they doe little events with no influence. In high-audio ...
|
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...
|
I don't suppose the input tube was a 437A?And perhaps (at that price) silver trannies? I have never never knowingly heard silver trannies (apart from my Ortofon step-up), and I wonder why anyone would pay that much for them when amorphous ...
|
Of course I meant the "niche product" appellation as a joke, skewing only slightly the original question of why are there so few Melquiades extant when the idea has been out there for so long. And you only underscore my point whe...
