Is it bad to have my sub near my comp tower?

I doubt so. Unless you’re playing something at 100 db I don’t think that the vibrations would be strong enough to actually cause your PC to vibrate so much that it would cause things inside to rattle and fall out. Besides, don’t the manufacturers of such hardware have drop tests? If they can survive these tests I don’t see why vibrations should cause any problems.

However, try checking for dent marks on your wooden floor. If you see evidence of slow PC migration then perhaps there is something to worry about.

(This is all from someone just using his brain and no other deep knowledge about PCs, FYI)

Unless your sub is putting out some nice bass, you shouldn’t have to worry.

If it is pumping out the wattage though this could lead to the heads skipping on the hard drive ( if its not a solid state disk ) or the ide/sata cable could come loose.

Manufacturers do have drop tests for laptops, but not desktops.

I don’t know of many people who carry around their desktop unless they are going to a Lan party :)

Yes! It is bad! Think about this… Magnets are inside every speaker. Your hard drives are running at 5400 – 7200 RPM. That’s pretty fast! That’s faster than my engine redlining. The fastest way to wipe a hard drive clean is to get it near a magnet! Think about 7200 RPMs spinning and hitting the internal top of the hard drive and just stopping.
I run an IT business and as a precaution I always keep sound equipment on ground level, ear level when sitting and also speakers at ear level when standing. I once knew of a very frustrated computer user that had to keep replacing hard drives. What was actually going on was that they decided to decorate their tower with magnets! :D Wow!

@straightroadtosuccess im sorry but theres no friggin way the magnet in a sub could damage a computer, let alone stop the damn hard drive. Have you ever tried to actually stick anything metallic to the outside of your sub box? It doesnt. So how it the magnetic field somehow traveling all the way to the computer, through the aluminum case into the computer and then some how still having enough force to stop the HD (or even slow it for that matter)

@straightroadtosuccess has a good point. When I bought my speaker system for my computer, it specifically mentioned that the sub was unshielded and so must be kept at least 3ft from any form of magnetic storage. My parents’ home theatre system setup guides said that the best bass is achieved when the sub is in one of the front corners of your listening area, so for the sake of sound it may be best to keep the sub to the side as well.

I think the magnetic field might do more damage than the vibrations do.

Check if it’s shielded, and do what FireMadeFlesh said: keep it to the side.
You’ll feel sub anyway. if it’s behind, in front, or to the side of you. Low frequency sound doesn’t have a real direction we can pick up. So i’t doesn’t really matter where you place it.
A computer under the desk is much more beneficial due to the noise it makes and the connection capabilities you need to your desk. So set the sub aside

The vibrations will harm it, but not that much. Trust me-I’ve done research on this before, and if a sound matches the spinning frequency of a hard drive then just a little bit of nose will hurt it a bit, but you’d have to play it very loud to cause any permanent damage.
