Logitech Z-5500 THX Bass Tests

Logitech Z-5500 THX Bass Tests through a Optical line. Second song is a bit long though. This video does not do justice as to how great these speakers really sound and how loud it gets. The bass gets so strong things started falling off my desk and nearby shelves. However, the subwoofer did start to overheat towards the end of the last song but keep in mind I was pushing it to its limit.
