Rather stupidly, I left the rear speaker in place when the old Rover was
having a new rear wing fitted. Which is welded on so removing the old one
would have produced some steel swarf or whatever when drilling out the
spot welds - and a lot of it has ended up in the speaker. It's a fairly
pricey aftermarket 6x9 with a pair of tweeters mounted on a post in the
middle, and the swarf has got down between that and the voice coil former.
Any ideas on how to remove it? The post itself isn't the magnet pole piece
- it appears to be plastic. No idea how it's held in place - there are no
wires to the tweeters showing.


If it's a good speaker with a very powerful magnet it might be time for
a new speaker.


Agreed, and just put it down to experience, unless you're prepared to
muck around with a pair of sharp tweezers for a fortnight or so...

Fortunately modern speakers seem to have a sort of protection of the
voice coil at the front by way of a sort of mini dome.
