Default Grill FOAM -- JBL L100 etc.

Badger me if you like but I've decided to use a foam for the grille covering
on my subwoofer, or at least try it.

Dispersion problems down there are not the concern as much as air movement.

Has anyone used a foam?

Certainly it needs to be open cell and structurally strong -- anything I can get on McMaster Carr etc? 3/4" thick probably.

The JBL used what? They just say "poly" foam -- which could be a number of
things.

The JBL was a very open celled foam.

You is the man.

I love new sources for fabrication materials -- that's a good one.

Thanks.

Wonder if the color was dyed in or actually painted on the JBL?
