Dave Glackin interviewed Dr. Bruce Edgar in his home, prior to the 1996 WCES. A follow-up on the speak...

Romy, I understand you are saying that a midrange horn rated flat to 300HZ should really be crossed at 600 or 1200 HZ. That claim doesn't make sense to me, esp. with a 24 db or higher crossover (active). Unless you are saying that hor...

Hi Romy, As a recent convert to horn-speakers I have greatly enjoyed trawling through your website and I have learnt plenty not only about horns but also about questioning my own motives and the desired end result of a possible "from scratch" spe...

If you know how in some optical systems imagery get destroyed when an aperture getting closed to F64 or even smaller, then you understand what happens in compression driver when frequency get higher and spaces smaller. Yes, the proximity of wavelengt...

Jessie, I have moved your post to your 45Hz horns thread but then decided to keep it here as some of my comments would be about entire system not only about your midbass horn. Anyhow, there is nothing there to laugh and it is pleasant to see that som...

[quote user="kodomo"]I dont think a standart klipschorn would satisfy the cat. I had one, then I heavily modified it and in the end I built my full scale horn system. I still keep that modded khorn system as a second system.If I may suggest, if you u...

OK, this dose make some since, become I understood you that it droops after 300Hz.
I wonder what made you to select the 300Hz as a crossover point – the currently existing...

Paul,I have not heard the synergy horn or any speaker with that design. Here is what I am talking about:http://www.yorkville.com/images/products/u15_cut_sm.jpgIn this particular case there are 3 mids and 1 tweeter driver sharing the same horn.This so...

The room is beautiful, and I love the tree stump "rack" with the amps, it is clearly a work in progress, but they already put in the "Western Electric" badges on! It talks a lot about their priorities I guess!They have what seems to be a midrange ...

[quote user="Romy the Cat"]
Drdna, generally I would not agree that your assessment of the EdgarHorns is correct. There is nothing fundamentally wrong in them that would prevent them to "disappear" in the room. [/quote]Well, this is good news.&nbs...

Hello Romy, thanks for your guide.I've been thinking and I feel that some basic upper bass channel ideas are forming; they a result of, as you say ,"organic" derivation from the rest of my acoustic system. I am pretty excited about this idea i have. ...

It is a shame that I keep finding threads about a 300Hz compression driver channel, that ends abruptly. I have been trying with a not-so-exact Goto S-150 replica (~1.7m deep, 75cm diameter mouth), and I know of another fellow in Sweden who tried the ...

Haralanov, I guess you mean to say disconnect the tweeter on one side of your playback? not the whole left side of the playback...When you use compression drivers it is very important to design the horn taking care of the high frequency response. ...

Thanks for your quick reply. I have been to assistance audio`s website, however was unable to find such model, but is possible they just disassembled the tweeter or whatever.This is really interesting news, about their violin reproduction, me too wou...

I'd like to ask if anyone sees and appreciable problem with the following.I'm trying to arrange a 4-way, 3 horns sitting on top of a big bass box. As I have it the 42cm midrange horn (800-8k) is in front of the 95cm lower midrange horn (250-800hz). T...

I realized you meant Midbass when you wrote MD. I agree that letting the midbass horn run full range on the bottom is not a good idea. My point was try the bass channel (Aura 1808) run much higher and share the same crossover as the midbass when cros...

I used to have Edgar 80hz straight horns and this was my only experience with short midbass horns. I did not like them in my system and sold them. Lately, I have been wondering about these designs in general and is there such a thing as a good soundi...

[quote user="drdna"] BUT, I think it is more exactly what you say that the midrange horn is round and the lower midrange horn is rectangular. They sound different and it is more easy for me to hear the presence of the rectangular horn. [/quote]...

Jessie, I pulled posts from Macondo Axioms thread and encapsulated them onto a new thread dedicated explicitly to your project. I hope you do not mind.

The “best midrange comes from compression drivers”. I see somebody like Haralanov would be very much opposed to this comment. The irony is that I would be opposed as well to this comment. I would say that the best midrange at over 107dB sensitiv...

Number one, that I'd like to run by you guys due to it's simpler nature and closer to reality execution is the idea I have been thinking about. No first hand experience with any of this.Say we use something like altec 1505b multicellular horn that sh...

I have identified a direction for my next speaker system. Whether it is a good one or not is a different topic -- I think it's a good one because I've lived with my current horn system for 10 years and have since developed an understanding of it's st...
