Default Replacing speaker grille foam

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
tempered virgin linear response low distortion acoustic audiophile
expensive foam?

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.

Open cell acoustically transparent foam will do it.
Something like this

Difficult? It's foam and mostly made of air, you may have to learn how
to operate a pair of scissors or a craft knife. any small child should
be able to show you how to do that. A bit of practice on a bathroom
sponge and you should be good to go.

Save yourself the hassle, cut one leg off a pair of tights and pull that
over the speaker, could add to the aesthetics, fishnet speakers anyone?

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.

Interesting - this is to shape a piece of foam, or simply to trim it to
size where the edges aren't seen?

I'm told the usual way to get a perfect edge etc is to freeze it first, so
it doesn't distort when cutting. But if a moulded shape like many foam
speaker grills, even more difficult.

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.

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.

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

They look like

Why not just leave them like that?


Well, they've been thus long enough...

I think they'll look nicer with grilles.
