Ever since you 1st mentioned the 'thump' issue, I've been paying close attention. While the EP500 and SMS-1 get fairly close to what I'm looking for, I don't know if I need a second sub, more room treatments, some more attempts at sub placement, or yet MORE experimentation to get what I want. It's a difficult puzzle to solve.

Your bass 'needs' appear to be similar to mine.. I don't however, have as many opportunities/means as you do to explore the possibilities...so I'll be eagerly lurking! \:\)
