Travis, to answer your original question about your sub damaging stuff, I say no it likely won't. I've had subs sat next to my PC before and even at full bass (that's when things around the room start vibrating), nothing was damaged at all. Obviously you're not going to be using 100% bass all the time, so the sub won't vibrate much at all and shouldn't damage anything.
Thank you for a well thought out answer :good:
