Musique Concrete stopped selling horns a while ago and are now manufacturers of commercial horn loudspeakers.As for the "Grande Castine", I think that the MF section is in fact the MF/LF section and the frame is indeed curved.Cheers,Ric...

I've missed that they have some prototype or whatever.Can you point me directly to the article where they describe it?I have no time nor interest to go through all of them on the mentioned page,as I smell it's all a "cold-fusion-in-a-glass-of-water" ...

If you do go forward with the concrete speakers/woofers, I will chime in with some concrete mix specifications.You will want experimental batches of the concrete mix done before the actual production mix.zz....

[quote user="cv"] Well, the Cogent (Steve Schell and Rich Drysdale) boys are building just such a beast: field coil magnet, (possible) permendur polepieces for >2T, Fs 70Hz, throat - dunno, but at least 3" dia, reduced compression ratio relative t...

What would be a better material for horns, specially large ones, steel/aluminum or polymer concrete? Do metal horns be the right choice in general?
I just remembered I could ask some favors and have large steel/aluminum horns mad...

Well, I have a theory that the rough surface may be helping to attenuate multiple back-forth axial reflections, but from what you say, it may be that it results in - what's the proper term? - irregular as opposed to laminar flow at the surf...

Some of you
have already seen my old posts about the 2 pair of concrete midbass horn a
friend and I built a few years ago.

[quote user="Paul S"]
The more-driver/more-power method has in fact been used to very good effect in rooms that +/- eat bass. The set-up I remember had about 8 515s per side and LOTS of power that I suppose it did not actually use very often; but...

I've just bumped into an "architectural" installation of concrete horns built into the house:
I know that most north american houses are not built this way (concrete structure and walls) but it will at least show you what can be done.Cheers,Ric...

Hi Romy,Got my new Le Cleach tractrix horns (320hz) for the Vitavox S2's. I'm x-ing over at 600hz with 2nd order 12db/Octave which I know is barbaric for you but it is all I have for the moment. With the new horns the S2s are puttin...

Once you have all these contacts come-up with a concrete mix, let me see it if you would like my opinion. I will let you know if I agree or disagree & possible improvements.IMPORTANT: Is this an existing room? Is this room "on-grade"? Do not f...

I have no comments about it besides assuring that the company that state all of it does crap in term of Sound. Still, I find that the way in which they think about construction of the walls of their back-loaded horn worth very much attention. Tak...

Though I have difficulties warming to the idea of the "headphone" arrangement for these horns, I do understand that we are talking about loading the room. Similar thinking lead me to consider setting large horns behind the listener in my own longish ...

Paul, I am no expert on tapped horns but I think the main (40 year old) principle is that you join the back wave of the driver with the front wave, now in order to have the 2 wave fronts meet, the back wave should travel a certain distance depending ...
