Well worth the money
Crutchfield Customer Review (What's this?)
I bought this to replace a Polk passive subwoofer over 20 years old, part of RM 5000 set. Huge upgrade that complimented and improved the new Polk TL3 satellites I bought as well. Great sounding bass that you can easily dial up for room rattling sound. Nice thump that I never had before during music listening and home theater watching. So glad I finally upgraded.
