Dual PC+ subs will bottom sooner or later but you should be able to hit 115-116db in 16hz tune in a 3,000 cu ft room.

I say watch WOTWs at the loudest you would ever tune up your system. If the subs don't bottom out, you should be fine with anything else you play at or below that level.

Also, the PB10 has a limiter in it that won't let the sub bottom out. The other SVS subs don't use this same limiter and will sooner or later bottom out.
