This wooden multicell horn photo came from Michael Christ's web-site, but the web downed since a few months ago.
Those look great!
I have heard the Altec versions and they were fantastic.
Haven't seen Michael' site in some time, it does seem to be offline.
Maybe he can be reached by email?

just put the @ sign where it belongs.

Thank you panomaniac, do you know any diy web-site mention about the wooden multicell horn project?
And how about this wooden horn? Anybody know it? Is it a diy or commercial product? Where can I buy it?

That horn is an Onken, I think. Onken drivers too.
It is in a very large and famous home installation in France. It has been reviewed in several magazines and websites. I'll see if I can find the links when I get home. Maybe that's were you found the photos?
Talk about bass horns!!

Here is a link to the system pictured. Belongs to Mr. Roggero in the south of France.
Giant System.
Article says those are Onken multicell horns and Onken 2" dirivers.
Enjoy!

May I know where is the Onken made? I found there band name on the forums only but never seen there product, are there the band discontinuous?
Onken is Japnese. I think they are still in production.
You'll have to cruise the Japanese sites. But Onken should be well known in Hong Kong. Right?

No! I never heard this name before until I found it on the forum, I also search it in Yahoo Japan, but no result!
Just do some research on the basic design.
They can be built.
Well, anything can be built.
The construction can follow along the lines of the basic Altec/WE multicells. Of which this is a copy.
A problem will be at the area near the throat. The wood has a relatively large cross-sectional area (thickness) - which means that there will be reflections where the cells are combined, unless you do some very fancy wood working.
Also, a major issue will be the damping of the wood walls. The sound pressures in the horn itself are high. Damping is needed. Some of the metal horns were encased and potted in "tar" to make them stiff and damped, to solve this problem...
I'd say that to do a credible job in wood, you'd probably put in 100 hours in a well equiped wood shop... but they'd look good! 😀
Myself, for home use I'd prefer a lower frequency cutoff single cell horn, probably a Tractrix...

Hi,
A forum colleague, Petter, on Hififorum.nu in Sweden is just about to finish a very nice pair of multicell horns. If you can get some-one translate for you, you could follow his work. Look at the pics, they're amazing.
