Probably doesn't matter too much really. Since subwoofer magnets are still using Ferrite magnets, which are actually pretty weak. Thats why they have to be so big in order to dish out the power. And even then, while the magnetic 'field' is still generated near it (like around CRT monitors) its not nearly powerful enough of a drag to cause any harm to a HDD.
But with a Neodymium magnet (HDD magnet of choice
), you could have a 200lb ferrite sub magnet lumped down into a 5lb neodymium magnet and probably have twice or thrice the power with the neo. But problem with neodymium magnets, is while they are EXTREMELY powerful, they are vulnerable to heat. Too much heat = dead magnet. Which is why subs don't use them, but a lot of tweeters do, since not much heat is generated with them.
My point is, sub magnets really don't have much pull except in their 'sweet spot' outside that is a mild field of magnetism, hardly powerful enough to skew the data written by a Neodymium HDD magnet.
BTW, these two puppies can lift over 40lbs each...not bad for being a little less than a inch long and 1/4 of a inch thick.
And see this thing...it has 800lbs of pull force...800 lbs!!!
just scroll down to the supermagnets part)
If you were in the middle of a 20x20 room full of computers...this thing would probably be powerful enough to wipe clean every HDD in the entire area....and maybe even drag them towards you.
