I have an old pair of speakers whose foam grilles turned to dust.

Can they be replaced with any old thing? Or must I obtain special

I'd be inclined to use acoustically transparent foam. At the very
least, you
need open cell foam.

And how difficult is this stuff to cut?

Easy. Scissors or a very sharp knife (Stanley knife/scalpel).

Wilmslow Audio sell it.

It's no longer available in the size I need for my (now
semi-retired)
speakers, so I just took it off and threw it away.




If you get the foam from Wilmslow Audio (who are in Hinckley or
Nuneaton or somewhere like that although they started life in
Wilmslow) get some Tygan grille material as well. You will probably
have to take the existing material off to fit the foam, and Tygan
shrinks under heating (hair dryer) to give you a nicely tensioned
appearance.
