Hard drive on top of subwoofer?

I know conventional wisdom is not to do it, but I have to ask:

I am running out of space to mount new gear that I want to audition: an ideal spot would be on top of a Rythmic 15 inch non ported sub woofer

I have a NAD M50.2 that contains 2 hard drives and a CD drive that I would like to place on top of the sub: I would use Vibrapods under the NAD feet

so is the answer still a no, don't do it? or is it something others have done? would it affect operation or could it damage the NAD?

With 20 subwoofers in a 14 by 11 listening space. I have always found that it does not make much difference , worrying about hard drives, seeing as if I cant keep hanging pictures on any walls without getting unwanted vibration noise, and seeing as, the vibration on my wall mounted shelving is probably close to being right on top of some subwoofers, I doubt you will have many issues.

You may wish to keep a complete extra hard drive , cloned in case.

I have had over 15 drives subjected to a lot of vibration, and never had any performance issues with the drives. This is with all those drives in desktops on a shelf directly above 6 ported 15 inch subs. and the rest of the subs designated in left and right channel positions.

It would not hurt to try and dampen them off as you are doing. All the best!

A Good amplifier requires a adequate power supply, It does not matter what the amplifier is capable of if the power supply will not provide the power required. Most amplifiers have under rated power supplies. It is up to you to make sure you get the ones that are least under rated if at all.

It won't bother a hard drive at all, even without the feet, though they might be useful to keep anything from rattling.

If your subwoofer ever plays a tone that decays in amplitude, then the magnetic field from the woofer coils could demagnetize the hard drive .

Why don't the magnets on the speakers in a laptop do the same to the laptop HD? They're a lot closer to the HD than the magnet of a sub driver ever could be.
The reason is that a driver magnet has a permanent field. Back in the days of recording tape we used alternating field electro magnets to erase tape, and even those had to be virtually touching the tape to be effective.

thanks for the comments

I moved some gear around and made a place for the M50.2 in the rack where I am sure it will be much happier
