    I needed a sub as mine bit the dust. I am saving to upgrade my speakers and the price was right on this. It has a good range and so far has done a very good job.

    I hate the size of these things. I wish we could get the sound quality out of something that was 10% of the size. But it works well so I can’t complain much.

    This Subwoofer replaced the old one that was no longer working. I looked at several and the salesman at Best Buy answered my questions and I decided on this one. I’m very happy with the purchase. The Geek Squad technicians set up the New TV along with this subwoofer.
