Thanks for the detailed answers. I will explain my setup.You are right about the dipole bass correction instead of the injection channel. Since I am waiting for both a subwoofer and the Fane Studio 8M and their horn, I am using the 12" as a b...

Listening the argument of the field-coil’s people I note that they constantly stress the demagnetization subject of the driver’s magnet, advocating that with electromagnet “the field coil will always produce the same strength now and 100 years in the...

Collin,
I do not remember that I wrote that Trios are “duller”. In fact I do not remember I ever wrote anything about Trios in comparing to my current hors. Furthermore, my “Macondo” derived for the Trios and practically fully inherited the Trio’s ...

hi alli found a company in china wich can produce the compression drivers on my request. has anyone the exact specifications and drawings of the vitavox s2 driver ? that's of course essencial to get them made. i will also send a email to t...

Josh, I am not sure what you want to say. If you looking to name the reason why you like the sound of Gotos then you are guessing as much as anybody else. I can tell you even more. I very confident that the Goto folks themselves are guessing. I do no...

[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...

I built a prototype of a Avantgarde Trio in newspaper and tape, with the Beyma CP380/M, Community M200, and the Fane S 8M, and I also used a Behringer CX3400 and a 45 tube amp. CX3400 is soon replaced by digital active XO.Paper may have made the midb...

For those seeking some decent compression drivers that don`t cost fortune, I can suggest to try the Eighteen Sound ND1460A compression driver. It has aluminum dome and polyester suspension and 1,4 inch exit throat. Does it sound like S2 ? Probably no...

Hi Romy, Hi Jeffrey Steve and I have been working on the bass compression driver for quite some time now, about 3 weeks ago we made some design changes that really paid off, as of now I'm convinced that a compression driver is...

John, I see where you go with it. I afraid that I will not be making my drivers – I have no idea how to make them in order them to sound the way I need. I have no problem to design and to make 4" exit compression driver or to undertake a project to r...

Audio Federation have publish some images from the Silbatone room at CES, even it is in their new idiotic format of the “magazine” but they still visible.

Dolph,As anything else in audio I do not see the problem that we as experience in worsening of FM as technological problem but rather the failure of human factor. I have no problems with the fact that FM is digitalized and that most of the “live” FM ...

[quote user="steverino"]FM is Analog Signal Processing vs DSP. The compression aspect is only really intrusive on orchestral works. Pop and jazz are already compressed and chamber music presents a more limited dynamic range if not limited contrast. B...

[quote user="Michaelz"]Some drivers have a rising db curve from low to high frequencies. The horn may help with flattening the FR. If the FR of a given coaxial compression driver is flat, I would agree with your conclusion.[/quote]Mi...

I think the usage of Romys Injection Channel has misguided you to think it was implemented because of a certian lack of tone or some sterile sound, nothing of the sort, I cannot blame you for not having listened to Romys system, but theo...

[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...

[quote user="rdrysdale"]….as of now I'm convinced that a compression driver is the best way to go for fast, detailed and dynamic bass. The compression ratio needs to be just right, and the horn needs to be right, when these two are working together p...
