I found this home theater subwoofer on freecycle. The owner had sold the amp that was attached to the back. I'm guessing the shipping on the sub would have out weighted the benefits of reselling it since it is the size of a ottoman. Apparently the sub works fine and is only a few years old. It looks immaculate from the outside so I have no trouble believing this. I am now looking for an appropriate amplifier to match my sub. I will also need a receiver or maybe some type of combination of the two. I am new to home audio but the subwoofer has given me an incentive to really start planning and building a system. If anyone has any advice on what I should be looking for it would be a great help to me. I have searched google to no avail.
