There's been a lot of interest and work done with a horn
design called the BIB (Bigger Is Better) first built by Terry
Cain from some plans in Japanese. All of these BIBs use
4, 5 and in one case 8 in. drivers but those would be huge.
The design is like a Voigt Pipe with an extra fold that
fires out the top instead of the bottom. When placed in a
corner, the walls load and essentailly increase the
flare of the horn mouth or terminus
With the driver specs that you have the gang that's
building the BIB site at:
http://www.zillaspeak.com/bib.asp
can give you some dimensions.
One design element of that site is it's not real clear on how
to move around. Click in the red "how To Build a BIB" to see basic design principles. Click on the speaker logos for alignments and
specs for individual drivers.
Have fun.
