I guess nobody really answered your original question.

Between EP350 and PB10, I think you would find that the 350 plays a bit louder but the PB10 goes deeper. Despite the smaller driver, the PB10 cabinet is almost 50% bigger than the EP350 (6000 in3 vs. 4400 in3) which does help a bit.

For a living room system, there is a lot to be said for the nicer size and finish of the EP350. You may get more of what is often called "slam" (which seems to be more around the 30hz range) from the 350 but I haven't seen any good comparison tests.

The PB10's strength is that it goes several hz deeper into the low bass than the 350 before rolling off. Subwoofer buying is full of difficult tradeoffs ;(
