It's a sad day. My 3-year old, $99 Dayton / Parts Express 10" "Tiny Mighty" subwoofer is dying. It's buzzing in stressful situations and occasionally it's producing a "whooshing" or feedback sound that sounds like electronic wind. I've opened it up and can't figure out what's wrong. Annoying as hell. So, I ask you all, what now? My home theater consists of the original JBL NSP-1 package, a Pioneer 811S receiver and a JVC 48" HD RPTV. Would an SVS PB10-ISD be a mismatch for my humble setup? Seems like a good option for $460 shipped. Should I just get the $125 second revision of Tiny Mighty? Thanks for the help.
