I don't follow why I'd need grille cloth as well as foam (originally,
there was just the foam).

They look like

** You cannot use flat foam rectangles for that speaker, as the woofer is mounted on the surface of the baffle and there HAS to be a few mm clearance in front of the cone/surround to allow for movement.

The originals must have been sculptured to prevent cone strike.

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

And how difficult is this stuff to cut?

Foam of any type is very difficult to cut neatly. Best way (if
possible) would be to use a proper speaker fabric. You'll find it on
Ebay, etc.

The foam rectangle would be inset into the surround of the speaker. As I
recall, the original had square edges and nestled in reasonably
securely.

So needs nice accurate cutting. Good luck with that. ;-)

If I were to use speaker fabric, I'd also need to create a frame that I
could fit into the surround. Foam sounds easier, if not as attractive.

Making a wood frame and using a fabric is likely going to be easier way to
get a decent looking job. Unless you can buy the original foam mouldings.
IMHO, of course.
