    Blast blast. The best Subwoofer money can buy and it is not expensive. I just bought another one for my game room.

    I needed a little something more to give my home stereo the theatre experience and it performed very well. Plugged right into my stereo (with the provided cable) and power, that was it. It also lets you adjust the amount of base that you want. I recommend if you need a little extra base.

    When you experience the lower end human hearing action movies take on a sense of realism. This sub provides that sound you can only get in a movie theatre or at a live concert.

    Great value for a subwoofer that adds deep bass for movies and music in our bonus room. I keep the unit on because sometimes it turns off if the volume is low and has a hard time kicking back on.
