I have the Altec Lansing 641 speakers and as many of you may know, the subwoofer for this setup is the size of a mid-size tower and weighs about 50 pounds. I want to put this beast on wheels (forunately, there are already rubber feet, so I just have to replace those), but I was also thinking about adding some heavy duty case handles to the top of the case. Since I take my computer back and forth from college, this would make transporting the subwoofer much easier. However, could this effect the sound of the subwoofer? I'm assuming it would, so that's why I'm asking, but I could be wrong. What do you think?
