I am searching for a subwoofer. variations abound to dizzing ramifications. I want a sub for a 1300 sq ft garage that can make the neighors cringe. It seems that I can purchase anything from an 8" sub with 1600 wts to an 18" with 200 wts? I would like wall shaking, ground rattling "crisp" response. Cost would be an issue above $1000 dollars. Please advise. I am a neophyte at the technicalites. Premieum on crispness, not mud.
