    This is no where near as good as the Infinity it replaced but OK. Definitely nothing earth shattering. Good price when on sale at BB.

    Base sound is enhanced. Note that you do need to turn it on and off separately from the rest of the stereo.

    I got this at a reduced price, so while it is certainly not the most impressive sub I've ever heard, for the price I paid, it was a steal.

    It is good for small rooms. It just didn't have enough power for what i needed it for. I would recommend it if you're looking for good deep bass for a bedroom or a smaller living room.

    Sounds really great when it works, but keeps cutting in and out. For some reason, the auto feature does not work very well. I will be watching one scene of a movie and the sub clicks off, a minute later it clicks back on with bass. Annoying to keep hearing the constant on/off clicking sound every few minutes.

    No, I would not recommend this to a friend
