John Hasquin showed up a couple days ago and suggested that many of modern compression driver manufacturers design thier products to get the "best" publishable parameters while completely disregarding any basic horn design rules and actual sound resu...

Well, I'm hoping the Azzolinas have something going for them. After all, it's not about theory but results. They came recommended as decent, so I invited them to be in my RMAF06 room. Yeah, I committed myself unheard, unseen. ...

OK, Romy, that EnABL stuff got my attention!I can't recall all of the bad ideas borne of good research, but this EnABL thing sounds a little fishy, and certainly it sounds too good to be true, as existing in a simple and really useful form. Can...

Gentlemen,
I suppose it is time to defend my sterling reputation here. The EnABL process does in deed work across the full frequency band. Works on all driver types and permits the very qualities that Romy seems to appreciate in the treated Linneum ...

hi romyi am listening now abought 2 weeks my orphean horns. when they arrived, i first connect them to my electronic crossover, and they sound horny, very bad. after i connect them to the own crossover, sound changed right away. now, that i heard mos...

If you ask me the compression drivers is like the jbl 2420/2470 design only with an other back chamber. And the low freq driver really makes me think of an old alnico driver of jbl 2220A http://www.lansingheritage.org/images/jbl/specs/pro-comp/2420/p...

does sound interesting. where are the flying from? ...

Maybe what we need is five channels to cover all the octave and two or maybe three drivers for each channels. You could then tune the contribution from each driver to get the correct tone for each channel. The only drawback is that it would require m...

A little update : Reading some recent comments in the "Configuration from Italy" thread: http://www.goodsoundclub.com/Forums/ShowPost.aspx?postID=12605#12605 prompted me to share what I've recently done. Yes its an obvious thing to do, but it took...

I set up today the framework in which I will be testing my Vitavox 15 inchers. It is a wooden frame from my bathtub with a driver screws to it, the massive sliding doors that squash the driver from both sides and cardboard that cover the wholes. This...

Agreed JD. Also I have seen silicone and other petro-based products in contact (or proximity via vapors) to cause certain foams to break down over a period of several years. They might have a similar negative impact on driver components and bonding a...

Paul S wrote:"typical "stereo" L and R separation is mostly an engineering hodge-podge". I do not disagree with that statement. I do feel the major advantage of stereo is not "stereo", but the separation of parts of the information in the signal ...

Hi audiofilofine.Nice drivers, although the picture is a bit fuzzy. Can you tell more about your drivers?Maurice....

[quote user="Wojtek"]I'd like to point out that Fostex 500 MKII is very much not sharp and artificial sounding. If anything it's an opposite -little too syrupy , soft and round so it blends with cone mid better than beryllium tweeter.[/quote]

Ok, since you people stop to drop the euphoric saliva around the Goto subject I think it would be worth to outline my interest in Goto. Not only worth but I kind of feel an obligation. I feel that my site surprisingly has become a resource that ...

[quote user="Jorge"]Andrew,Dont buy all the drivers at once, I would get only the upper bass horn drivers and maybe the mid drivers, you will have to play around with these for a while before things start clicking toghether, by then who knows, ma...

[quote user="de charlus"] I propose to array the drivers, and horns, as laid out beneath, from top to bottom;Ale Acoustics 160Super (15hZ-1000hZ, 110db/w)15hZ - 150hZ Lower bassVitavox AK 151 (50HZ-8kHZ, 100db/w) 150hZ - 350hZ Upper bass...

We understand that Charlus’ selection of drivers are not a selection yet but some kind of very preliminary idea of the drivers that he feels like he like. I said “he feels like he like” not accidently. I do not think Charlus, or anybody else in h...

Pierre, yes, I understand it. It kind or irrelevant what they destined for and yes, in domestic applications in context of low power we can use it lower. What I am saying is that as we do use it at extreme low range we deal with slightly overdamped d...

Does anyone really have the resources, and the patience, and the evolved audio/musical discrimination to develop a 4 or 5-way FR speaker system from scratch, including each and every driver? I can actually see a "theoretical" benefit in using field ...

If I were in your situation and have 2m long 100Hz horn that
I like then I would not dive into any 200Hz la-horns. Make your 200Hz horn up-to
let say 1000-1200Hz. Then take your 550Hz and run it from 1200Hz to 10.000 and
up. Vice and configure thi...

Hi Murataltuev,I have two horn based systems but the system that is similar to yours or Romy's is the one I am currently building. The drivers and horns are as follows.38hz - 160hz - Tad 1601b - Bass Array (4)160hz - 600hz - Supravox 285-2000 hornfab...

Well, Guy, I do not know what will motivate Mike when (and if) he comes up with his new drivers. Being a manufacture he will become also t industry participant and consequencualy the actual Sound would not be within is area of interest…. Anyhow, I al...

Hi Romy,Your the first person that I have seen that seems to have actually made PP tube amps work with compression horn drivers. It has been my experience that PP amps don't like the low watt operating range. I supose it all is a matter o...

The subject of electromagnetic, or as they called field-coil drivers, popped up at my site numerous times. (Look as it list of related threats). The advances or shortcomings of electromagnetic drivers are arguable, I have my vision, but it is not the...

I kind of fed up to receive those emails (I ordinary do not reply them) with questions and therefore I would a would make one atypical public statement and it will be it. I say “atypical” as I truly do not care about your purchasing habits, still sin...

Ygoh, Most of compression drivers have phase plug. A phase plug is very genomic center line oriented devise. A phase plug must be parallel to diaphragms and perpendicular to the axis of the driver. Practically all compression drivers have beggin...

Me again..In my search for another jbl 2482 I chanced upon a Yamaha JA6601 Driver. http://picasaweb.google.com/jbjbjbjbjb/YamahaJA6601It looks very similar to the one that produces these amazing response plots on the Azura 204 horn.http://www.azuraho...
