Hi Romy,as distributor of David Haigners products to Austria and Germany I think I should make some comments on your...hm...review of a speaker you have never heard.I will not comment on the theory of CD horns here. It should only be noted that the A...

scooter, that was a whole point – to see if the fundamental dilemma of the those designs was addressed. Frankly I was prepared to see some kind of interpretation of unity horn, not just blunt lock of any efforts in this direction. As is, the Vittora...

I think that most of us here consider horns to be decade devices. That means about 3.5 octaves can be optimally covered. 800-8000Hz in your case. Extending the "highs" another octave means a couple of things. If a horn is "too short" you do not get m...

I need to say that I do not like the Netherland-based company BD-Design. They do in my view non interesting products and their owner Bert, despite of being a more or less knowledgeable audio fellow have a tendency to patronize incredibly filthy audio...

The reticulated foam makes a difference and that is for sure. However it does lower the output. From about 1db up to 2.5db! depending on the amount you put inside your horns. Is it transparent? It is not, as it creates and audible difference even if ...

hi Dominic i made myself the same question regarding the high frequencies in the orphean horn. the reason is probably because this horn has no compression, and the horn length is not so deep, and the exit diameter is 2 inch, quit big. If you read my ...

thanks for the responses doc and romy-much food for thought- but what i'm thinking, or at least extrapolating from what you're saying is that the possibility exists that i AM measuring what i think im' measuring.i have a good friend who is very...

[quote user="Dominik"] I saw and hear thise horns on audio show in Waraw this month(I went 200km to this show only to hear this thing). It is La-horn 200hz, smaler horn is La-horn 1000hz. Drivers is BMS. Bass is TL. Orginal name of this system is ROC...

I did not see in your post any “sad truth about BMS”I would stick in the JBL 2440. It is relatively inexpensive. Has practically the same performance as the hipped JBL 375 and all together a good performer. It’s diaphragms are wildly available and it...

[quote user="op.9"]I now run my 'tweeter' amp 1st order high pass at 2200hz (driving BMS 4540nd in 1500hz leCleach horn) so my impressions might have some bearing on Romy's new amps. I was playing around with operating points and components in my sin...

To make the story short :) Autotech is a family business located in Lublin, Poland. Younger brothers graduated in mechanical engineering are cars and racing lovers - with scores in Europe as professional drivers and mechanics. One year ago Lukas wrot...

Yes, I did not realize that the price of £225 is for a PAIR; usually price is given per driver. I guess the £225 per pair is not and of the world but I still insist to pay 65 cents per 1 Euro as it use to do… In past I never dealt with Fane direc...

I never had that Selenium 405 driver. Generally the phenolic diaphragms are very tricky and might have some excessive softness and some luck of transients. Selenium also had a habit to load gap with ferrofluid – it also might slightly detransientize ...

user="kodomo"]Oh and the fundamentals channel although begging me to
play a wider range, more or less disappears and actually helps the sound to
have more volume (not loudness) when covering a narrower range. It sounds like

For home use almost any driver will go lower without burning up.
If you want specs, BMS and B&C will give you the right specs.
And then there is the tone...
I had 2490 play down to 200 hz in a 100 hz horn, of course they would only go up to 1 kHz ...

Very nice, Keith, thanks. The most interesting would be to access the “Absolute Tone” capacity of the Gamma. Frankly I feel that with TADs it should not be very too advanced as they are at BMS/TOA domain, only with a little TAD syntactic twist. Even ...

[quote user="jessie.dazzle"]Have you ever tried the Community M4? I'd still like to try this driver.[/quote]Yes, I think we had a convesation about in the “The Macondo’s Upper Bass Channel: what is next? “ thread, I have linked it to current thread. ...

I am not so impressed bout BD Design speakers. I truly hated the BMS drivers that they use and I truly hate the network of the blabbering cretins that BD Design built around itself. Any single critical mentioning of BD Design lead to a sudden sho...

[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 have no idea what it is but it is something… Take a look:

[quote user="stuck.wilson"] I just started using RTA as a method of evaluating my results with my own 2 way speaker system, and I'm finding that I'm ending up liking the sound of my system a GREAT DEAL MORE without the absurd notion that 20-20k is wh...

It is interesting… complaining about the fact that the “promising to be claver” Cessaro Horn using the TAD drivers (still it is not completely known as they said that that MD driver cost €4000) I asked myself: what else they might use? Really, ...

Art Dudley printed his review of Volti Audio's Vittora loudspeakers.

He said: “This is surely one of the finest horn-loaded speakers made in the US” Well, that is kind of dubious ...

Hi Romy
a good sound in a room does not depend only on the speaker chain, but essencially also of the room acoustics. Probably many of the Trio systems didn’t sound right just because of that…. I was at Holgers Home in Lautersbach back in 94. He ha...

I would discard the first part of your post. It is it truly irrelevant what Germans, French, Japanese or Brits were buying and what particular brand and in what time they consider as “fashionable”. It is know that Ebay or Akibahara popularity has...
