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: 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.
