I have 4 IB-18’s, of which 2 were used in an Infinite Baffle set up for a short period of time. Absolutely love what the IB configuration does! We’re in a new location now with no options for an IB setup.
My question…should I use 2 or 4 drivers based on what I can accomplish in this new location? Here’s what I’m working with (all dim. are approx.);
Newly constructed dedicated, constraint layer dampened, room – 12′ wide x 22′ long x 8′ tall – 2100 cubic feet.
Sub encl option (gross internal)- 19′ tall x 22″ deep x 140″ long. – 33 cubic ft. (934.5 cubic liters). Sub location, front wall.
2 drivers (200 watts) 4 drivers (350 watts) Sealed, heavy stuffing for both.

Any recommendations, should I trade better QTC for lower excursion and higher SPL… in this size room? Or should I go in a different direction?
