B&W MM1`s running hot ?

[basshound]

I have a pair of B&W mm-1 computer speakers, I don`t use them that often but when I do the top of the right hand speaker gets pretty hot , is this normal ? By hot I mean you can hold your hand on it but would be like touching a medium hot radiator.

They do run quite warm. I'm not sure but the amp may be using the aluminium plate as a heatsink.

If you're worried that they are running too hot, speak to B&W who might yake a look at them for you.
