If one corner doubles the output, woudn't a sub in the corner of the floor, and two walls triple the output. Here is my idea of a 2 cubic foot 36" along the edge equal lateral 60 degree pyramide sub firing into a shallow 48" pyramide reflector to create a rear loaded corner horn. I would use at least four to keep up with my Altec and / or EV PA speakers.
Edit; this is just a proof of concept drawing to figure out miter angles and does not nessissarily represent woofer or box size or number. I need to keep up with 100db/watt/meter speakers playing at 120db at 14 feet away.
This follows along the lines of a center quad 10" sub I built for a showroom 25 years ago.
