I really like this subwoofer which is amazing. I got it at a reasonable price but the only drawback was that I was led to believe it was new whereas it was not :it was a return where the customer changed their mind and the 3rd party seller and/or Walmart should have made that stipulation for me to make an informed decision whether I wanted to gamble on a product that someone else had previously . That being said, it looked as if no one had taken it out of the box and has worked properly. I am quite happy with the performance which was improved when I added a subwoofer pad, Love playing Neil Young's DVD Rust Never Sleeps with the track Hey Hey My My (Into the Black) with the volume cranked as I was at the Cow Palace for the show= the subwoofer really comes to life then...
