I bought an Epic Grand Master 350 earlier this year. Back in April/June. I'm just not satisfied with the output of the 350. I love bass in the loud movie scenes. The problem i've been experiencing with the 350 is rattling(bottoming out?) on the deep long bass scenes. I will back it down to take out the rattling but then it's not enough bass. Trust me I'm VERY pleased with it. It's great for everything. I just think I like to shake my house a little to much, :-).

So I'm thinking of possibly purchasing the EP500. Unforunately I'm not sure what to do with the EP350 then. Does Axiom do any sort of exchange with an upgrade? If not how would I sell this puppy?

Or would it be wiser for me to purchase a second EP350?

If an upgrade to a bigger sub works well I'll pry look at moving up to the M60's or M80's.

Thanks for any help.
