Just food for thought, I have the 12" supernova, it's unbelivable, the 15" is on ebay, I don't know the reserve, and these are not cheap regardless, but I feel if this could be bought in the 1200-1300 range, I honestly think it's the best sub I have ever heard, just my opinion, In may small room the (2) of them would blow my walls off, but for the right room, I don't think you can beat it. Of corse it depends on the reserve price, as I am posting this it's 910.00 and not met. Jon http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=5715583589&category=3275&sspagename=rvi:1:2
