Anyone has good info on this subwoofer? I read good reviews, but I will have to put alot of money (U$1200) and it is kind of old (1997). I could buy the Energy MS 12.1 or the Kliptsch KSW-15 for the same price. Or the Velodyne CHT-12, JBL S120PII or the Infinity IL120 for much less. What is the one to go with?
