Summary: I am very impressed with this. Amazing sound for the price. The only problem was one of the cables that came with the unit was bad, but I had another at home so it all hooked up quickly. The instructions are marginal if you need them, and some people might if they do not understand how subwoofers work. I ran a stereo mini plug from some powered altec lansing speakers with a subwoofer output to the RCA audio inputs of this unit.
Summary: Bought this to increase the bass on my TV. It works fine. Accepts RCA cables (red/black & white cables) for audio input from your TV. If you turn up the bass volume, it becomes boomy or distorted because dialogue is sent into it. Keep the volume just high enough so that you can feel the bass but no hear dialogue through it.
Summary: Adds some ommph to those sound intensive DVDs. My Sanyo Personal Theater System works with this little jewel. The design is fuctional, the bomb-like shape makes for easy movement. The subwoofer was even better at adding some ommph to rock & hip hop music. Outkast picked up 15 energy levels. Even Bob Wills' country swing got some bounce. . . To summarize, it earns 4 stars for the 30 Watt power performance.
