    This was my first purchase from a Best Buy Outlet and I saved over $300 on item. I was a little more worn than I thought but it works perfectly. To be fair, I bought it online so I was not able to view the item. The savings were too good to pay up.

    Works well to add musical low end to good computer speakers. It's a definite step up in musicality from the old Polk PSW111. I find this to be a really good choice when a higher-end HSU or SVS sub would be too much.
