    Would it hurt my shielded centre speaker (M7C2) if I placed it on top of my unshielded sub (REL 201)? I know it going to sound awful but its only temporary until I can find a way of attaching it to the wall. And on this subject, anybody know any neat solutions for fixing a M7C2 to a wall?

    Thanks,
    Ash.

    Shouldn't be a problem, the shielding is to protect the picture tube in your TV, not the speaker.
    Use a wall bracket for mounting the center speaker, try furniture shops or IKEA.

    Hi Reiner,

    "The shielding is to protect the picture tube in your TV, not the speaker. "

    That's just my point. To rephrase, will the magnetic influence of the unshielded speaker affect a shielded speaker in any way? Does being shielded work both ways?

    Shielding means the speaker should not create a magnetic field.
    It is actually not shielded in a way that you have some cladding around the drivers but instead a 2nd magnet has been glued to the driver with the opposite polarity. Thus the 2 magnetic fields will compensate each other.

    Does being shielded work both ways?

    I would answer that with no.

    To rephrase, will the magnetic influence of the unshielded speaker affect a shielded speaker in any way?

    I don't think there will be much effect on the unshielded speaker. Avoid if possible but you said it's only temporary, so I think it will be ok for the time being.

    At least I wouldn't worry about any damage of the unshielded unit but sound may distort if the field of the sub is very strong. Not sure if you can hear that though ...

    Thanks Reiner! Just the answer I was looking for.

    Reiner.
    I would point out that some driver assemblies do indeed use a shield in the form of a cap that sits over the magnet, usually formed from mu-metal or the like.
