I'm finishing off my budget home theater and looking to upgrade my old subwoofer. The room is about 11x27 with 8" height (floor level) I have a 2 tiered plattform for a total of 3 rows of seats. I have been eyeing the SVS25-31 but at 379 + SH, it a little more than I want to spend at this time (WAF). I have also thought about the EZTUBESHIVAP kit from CSS. How does the EZTUBESHIVAP compare to the SVS25-31? Any other sugestions of powered or un-powered subs in the >$300 level? I do have an older 2 ch amp to hold me over until I can sneak in a plate amp into the bugdet.
