[quote author=Circlomanen link=1121460151/0#5 date=1124132607]The four 12 inch version is an idea. I dont know how big it would be since I havnt done any simulations or anything.

I have ;D
It's big!
That is the next plan, to build a sub horn in the alcove.
Cross over somewhere around 40Hz.
A 15Hz flare will go flat to 20 Hz.
Steve Schell has built one, calls it the "big bottom horn."
Truncated to just the first 20 foot mark, it folds up into a box 8' x 8' x 2' and fires into a corner 4" away, where the corner intersects the exponential expansion of the horn, and the room becomes the rest of the flare.
A horn doesn't need four 12s tho, in fact he said a single 15 is more than adequate. .
