The DC biasing of filtering caps was something that I was advocating for years but recently I was pointed out that German Avantgarde took it a bit further. I did not use this method but it goes sound interesting. Read the Avantgarde’s document, the p...

[quote user="jessie.dazzle"]Do I understand correctly: AG used Fane 8Ms in the Trios upper bass horn?[/quote] Oh, no! AG in Trio’s upperbass horn used similar 8” driver with 103 sensitivity. That driver was bad and it made me to look for a replacemen...

Running in drivers...and the sound is getting better and better...just lovely.This weekend, I'll relocate my mid bass horns to fire directly out to the room. The angled baffles work very well for integration of sound with the mid horns...but I'll get...

There was a review of Avantgarde Trio by Roy Gregory at http://www.theaudiobeat.com/equipment/avantgarde_trio.htm It has some interesting and bright aspects, some unadulterated stupidity and some pure dishonesty, no different from the actual Avantga...

Angelo,
I care less about the “commercially available” objectives, honestly it is too boring.
However, whatever you do not be distracted that what you are making will be reminding Avantgardes. The Avantgarde Trio Classic (in vertical configuration)...

OK, I think I need to help to poor Rakesh to sell his Fanes. If he do not find his 50 buyers then he will be suffer from need to buy all of them as the ugly Fane people will not give him a break, selling o him as many drivers as he has managed t...

[quote user="Merlin"] If they are modifying conventional drive units by hand, the labour costs alone can be prohibitively expensive. The fact that they are using heavy Alnico magnets and coating the diaphrams suggests that these units do not co...

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...

Hi Romy,You should have to check Tom Danley's speakers at http://www.danleysoundlabs.com/. He has quite a few tapped horn subs and Synergy horns for PA, but there are people using his speakers at home, like myself. I have changed from Avantgarde Acos...

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...

[quote user="rdrysdale"]Romy, I just got a Vitavox S2 into my shop today. I notice that it has a very heavy stainless screen on the front, do you leave the screen on when using the drivers? It looks like it restricts about 50% or more of the thr...

You said are lucky to get hornloading down to 150Hz. Then I guess you suggest you will end up at maybe 175Hz. Hornloading a compression driver down to 175Hz is not too difficult and the horn will not be larger than the Avantgarde Trio midbass horn, a...

Tonight I finished two
horns at once. One was a shortened Goto S-150 horn that now has a
Fane S 8M, without back chamber so far. Dimensions are now 1.1m deep, 11cm throat, 75cm mouth. It is replacing the Avantgarde
Trio midbass horn r...

[quote user="Rewind"]Hi, I am slowly building my own Macondo. I understand why the injection channel is there. It brings some kind of softness that the compression drivers lack. [/quote] OK, but it is not how I feel about the service of injection...

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 ...

Romy,Very briefly. I am wasting my time writing this response, and probably yours as well, but let me again, as you say, bite the bait and respond anyway.[quote user="Romy the Cat"]
Did you ever ask why would I need it or want it? I laugh enough to...

[quote user="KLegind"]I had a look at the pic of your speaker just now - may I ask about the reasoning that went in to choosing a diffraction type horn?Also, your midrange looks like an open baffle type. What kind of back wave/diffraction management ...

For the past few months, I’ve been looking for a solution to a problem – how to recreate through speakers the same sound that I get through headphones. Why did I embark on this quest? Well although I’m quite happy with my headphones, I miss being...

Zagaja, posted an interesting document in the thread “Who builds horns?” It looks like Polish Autotech Company stated to organize their horn in some kind of complete systems. That is already something, a few comment I would like to pass,

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...

Rowuk,
