I dunno about on it, but near it is fine. Depending on the sub, not much of a worry with that little logitech, but it could actually vibrate the computer off.

But those were 15's.....
I had two 15s myself and I promise you are exaggerating. I have a 10" sub sitting on a shelf in my bedroom, and I have to be within an inch to feel any pull on a steel keyring I have laying here.

Bigger subs don't have more powerful magnets, they simply have larger ones. The magnetic field is larger, but not stronger.

magnetically, it'll be fine, vibration may be your only issue. The speaker magnet will be far enough away from the HDD to not cause an issue, plus the metal case will shield/soak up most of the field if it even reached outside the subwoofer case. I think vibration will be more of a worry, but if you have vibration absorbant mounts, it should be fine.

and TwoCables - I know you are being helpful /cautious, and relying on the manual - but really it is stated to combat the claim culture. Just like bleach has "do not drink" and silica gel packs "do not eat". The hillbillies need protecting. tongue.gif

The magnetic field would probably be enough to damage data on old floppy disks (remember them? biggrin.gif ) but for an HDD in a metal case, It's very unlikely to do damage. Oh and talking about old things, how many PC's in the 386,486, pentium one days had PC speakers (complete with magnet either on or just under the HDD carrier? You get my point I hope. smile.gif

They STILL build computers that way. I have a E series dual core from a few years ago sitting onthe floor next to me with a speaker RIGHT NEXT TO the hard drive bay. Seriously, is O is the speaker, it goes like this:

O| | And the drive slots in there on its side.

I still refuse to trust a powered subwoofer with a giant magnet on it being close to a hard drive.

Good for you. Doesn't make you right.

By the way, a powered subwoofer doesn't have a magnet any larger than one that isn't powered.


A powered sub is nothing more than a regular subwoofer with the amp built into the cabinet. I don't understand why you keep specifying this like there is a difference.

In fact, even the big logitech units aren't as big as you think. Typically they are large passive radiators with a smaller speaker inside. Mine for example has an 8" passive that you can see, but if you take it apart there is a second chamber with a 4" woofer inside it. Most computer speaker setups are this way, and the magnets on those things are much smaller than you would think.

TwoCables 06-06-2013 08:06 PM

Whatever. It's all up to pheria anyway.

 

(yeah, I don't appreciate the way you said "Good for you. Doesn't make you right", so we're done here. You're not going to get people to listen to you when you talk like that)

I'm blunt. You don't have to like it.

Doesn't make me any less valid.

cjp4eva 06-06-2013 08:09 PM

I would worry about the vibrations and not so much over the magnetism problem.

No, you're not blunt. You're disrespectful and rude and it seems like you're more interested in being competitive (it's like you want to win or something). You need to learn how to teach people.

 

If you want people to listen to you when you're right, then you have to calm down and treat the person as though they're your friend. When was the last time you listened to someone who treated you with disrespect while they were trying to correct you? It's not easy to do, is it? I don't know how you can expect anyone to listen to you when you're rude like that. You call it blunt, I call it rude. It was uncalled for. A successful teacher is calm and respectful, not "blunt" (or rude, aggressive, competitive, etc.).

 

Whatever, though. Just forget it.

 

I think this post serves as a good example of how difficult it is to listen to someone when they're confrontational, rude, aggressive, or "blunt". As you can see, it doesn't matter how right I may be here, it makes you want to fight back instead of listen.
