Is cabinet projection about how far a decent bass thickness is heard from the cab? or is it what size room can your cab or number of cabs support? here is my situation, I play in a room that is about 30x60ft with false ceiling and concrete floors. my aguilar gs-112 with SWR 350/RBI rack sounds pretty thick up to about 10-15ft away, then it thins out quite a bit except near other walls where I'd expect it to thicken up. I also tried the Carvin 600w 15x208 combo that the church has on hand. it was of coarse thicker more evenly across the room. I'm going to get another gs-112 on thursday and think this will help quite a bit. I have no real illusions that I'll carry the room, but I was suprised with the thinness of the sound. Its incredibly heavy nearby the cab, thinner about 10-15ft out? there are pockets of o.k. bass, but definitely thinner and especially not loud. or is some of my loss attributable to position of cab? its about 20feet from the corner on the 60ft wall.
