speaker hard drive damage?

[bl74]

I got a new guitar amplifier and it is pretty big.  http://www.line6.com/store/hardware.html?modelID=5.  
My room is not that big so i have to keep it near my computer, (about 5 feet away).
Would this cause any damage to the hard drive over a long time?

I think at 5 feet you are pretty safe unless you have the volume so loud it shakes your computer

Should be OK.
I hear that a subwoofer on top of your computer can damage the HDD as they are susceptible to damage from random vibration.  If it's a fair distance away I wouldn't worry about it unless, as Serrik said, it shakes your computer.
