One of the reasons i started looking into SVS is because i was never really all that happy with my EP500... i realize that might have a lot more to do with the way i set it up than the actual sub, but you're certainly giving me something to think about. I might as well at least compare my EP500 to the PB3000 in the new space before i decide to get rid of it.
