It was a BIG room; over 4000 cubic feet, I believe. All the real bass heads in attendance agreed that Craig needed two of any sub to fill that room. As for me, I had a headache from just one. Just the THOUGHT of an additional sub made me queasy, and gave me vertigo. I feel reasonably safe in saying that in any normal sized room, one will do the job in spades.
