Youl be looking at ~700litres ea then.

1x12" lab12 per horn ?
If you decide on a driver its easy if you fold the way i do.

The classic S style folding still works.That F3 40hz horn,has excursion minimum at 50hz(good for most music) and is 340litres :-)

That's a really impressive horn and article. Thanks for posting it here. Do you suppose you could make higher resolution images available? I think I'll drop a link over at the High Efficiency forum.

Illuminati (1st Degree)

-1x lab12 driver
-Throat 200cm^2
-Expo 6metre path
-Mouth 6000cm^2
-Rear chamber 55 litre
-Corner usage-

Low excursion point- 24hz,43hz.

100db/1watt @ 20hz 105db/1watt @ 50hz

100watt input 125db 50hz
100watt input 123db 23hz

with that 100watt input,excursion is great below 23hz,subsonic filter required.

I can cad it sometime if your interested.Probably just a big S folding.
Cheers!
