High Def Digest Reviews the SB-4000 Subwoofer

"An exceptional subwoofer capable of producing incredibly clean and powerful bass. The SB-4000 can really bring the thunder…slammed me with impressive impact…just about shook the walls of my house apart and equally adept with music as it is with car crashes and rocket blasts. It can reproduce deep cello notes with crisp clarity just as well as it can deliver an earth-shaking explosion. Highly Recommended to anyone looking for a high-end subwoofer without an exorbitant boutique price tag."
