Though I have an ep500, I haven't done the listening tests that would help me answer your questions from my own experience. From my reading on audio, I've concluded that (1) everyone needs a sub, (2) several moderate quality subs of varying types in various positions are better than one big sub. Accordingly, I have 3 lesser subs, now, and since my ep500 is ailing a bit, I've just decided to retire her.
