My 8yr old Definitive Tech powerfield 12 sub got toasted in a major power surge so now I am looking for a replacement subwoofer. My budget is $500 give or take but if I can find something for less that would be great. Our listening room is in the basement and is about 15x20. 75% of listening/viewing id DVD while rest is music,(mostly classic rock, blues and jazz). Any suggestions for me. I have done a little research and the SVS subs seem like a good bet, how do they compare to the other major (store bought) brands. Thanks for the help!
