I've been researching folded horn cabinets, and came across this site.
It appears to have some unique design characteristics, especially in the complexity of the horns. In essence, they're incredibly efficient, and according to owner/builders, great sounding.

One of the startling models rely on 8" and 10" woofers, to drive a super loud boxes that compare with 15" and 18" monsters that require 8 times the power to reach the same SPL.

Check out these models: DR200, Titan 39, and the Wedgehorn. They look like great prospects for a live venue.

I was surprised by the technical know how of the speaker designer. HE knows acoustics - fir shir.

What was shocking to this fan of the Acoustic Control 370 bass amp, was his refusal to make 18" folded horns. His answer is a picture at: http://billfitzmaurice.com/phpBB2/viewtopic.php?t=1130
The big cones can't handle the stress of a folded horn!
Go figure...
