    Place them close to a CRT TV, turn on the TV and play some music.

    Then use a compass.

    BTW, if you don't have the only commmon device that is affected by proximity to a nonshielded speaker, what's the problem?

    I have a small Micro server tower, it has Harddrives in the tower obviously, I want to place it next to a speaker, as it is the only real place in my living room i can store it for now (Out of reach of little fingers, If you look at the pic below you will see to the right of the pic is a unit, and a speaker wall mounted above the unit, I want to place the tower on top of that unit, my fear is the magnet is the speaker and my Harddrives

    I would be more concerned about all of the electrical noise from your server effecting your sound system rather than the other way around in your setup.

    As larkone says, the interference other way round is likely to be of much greater significance.

    Can we assume those are Q Acoustic speakers? And can you give us the exact model number. The first place to start is the owner's manual and the Q Acoustic Website, and see if the speakers are listed as shielded.

    Needing shielded speakers was only a problem with the old Tube/CRT type TVs and computer monitors.

    As an alternative, if you are adventurous, you can pull the Bass drivers from the cabinets. If the bass drivers have a steel 'can' over the magnets, then they are shielded.

    Here is the identical bass driver with and without the shield 'cans' -

    Shielded -

    Dayton Audio DC160S-4 6-1/2" Classic Shielded Woofer 4 Ohm 295-308

    Not Shielded -

    Dayton Audio DC160-8 6-1/2" Classic Woofer 295-305

    My personal advice, find some other place to put the server and train little fingers to keep their little finger off things they shouldn't touch. Rather than child proof the world against my kids, I think it far better to world proof my kids against the danger they will encounter in life. Still, I confess it is always easier to raise other people's kids.

    But, there are plenty of dangers in your house, and you can teach your kids to avoid the danger, or you can try to cover and hide the danger and hope your kids don't find it. Kids can pull a TV down on themselves. Unless that book case is bolted to the wall, when your kids see it as a mountain to climb, they can bring it down on themselves. There are easily accessible electrical outlets. I see an electrical lamp within reach. I see audio equipment within reach. The world is full of danger, you can either pretend it doesn't exist, or you can teach your kids to avoid it or deal with it properly.

    Again, if you are unsure, then find a different location for the server.
