Arrgh! My sub just up and died yesterday, and now i'm looking for a replacement. There was a split second power outage/surge at my apartment, and niether the reciever or Subwoofer was on, but after that, nada from the sub. My reciever is a Sony STR-DB840, and the speakers and ex-subwoofer are AIWA's from one of those Home Theater in a box things from Best Buy. Anyway I am looking for reccomendations for a new Subwoofer in the less than $500 budget range. I live in an apartment, but I have either cool neighbors, or good soundproofing, as I have never recieved one complaint in the 2.5 years I have lived there, and have blasted the sound regularily. Thanks for any help!
