I'm looking for a round grille foam that is flat on one side and convex on the other. This is to cover a 15" sub. Parts Express sells metal grilles that snap over the woofer, but I'd like to find something in foam.
I'm sure I could buy a piece of stock grille foam and cut a round piece from it. But, it would be flat. The convex shape adds a nice touch. Any Thoughts?

Put JBL Monitor Blue grille cloth on the PE metal frames.
Zilch,
Will those metal grilles interfere with the sound at all? If one were to do the math, I bet a significant percent (40% maybe) of the area is blocked by metal. Seems like that would have some affect.

They move a lot of air through them in their "intended" application.
I'd be more concerned about them diffracting and diffusing mids, actually.
I don't know where to begin calculating the velocity and pressure drop.
Think port sizes, maybe.
You'll hear 'em if it's a problem....
Hipo, ask sonofagun, he may hava a solution 4 you!.
Send me some pictures of what you're trying to cover with some dimensions and I'll see what I can do.
40+ years of sacrifice...and for what???
I've drawn a set of plans to copy this cabinet design. The drivers are 2235H. I'm going to build two. I really like the look of the grille and would like something similar. My L100s have blue aftermarket foam. Also interested in opinions in the veneer. I'm thinking Rose wood with a high gloss finish might look very sharp. Problem is it won't match my JBL cabinets. Any thoughts.
Zilch, I bought a pair of 2225H drivers that have been re-coned as 2235H from a LHF member.

Oops! I intended to add this picture to my last post.
This is the look I'm going for in a grille.
SonofGun - anything you can help with? The driver is a 2235H.
If you compress a piece of foam to the back side of a piece of material with a hole in it, it should create a dome protruding through the hole.

Very difficult to solve such problems short of actually having access to the enclosure.
I can sell you some 1/4" foam which can be stretched over a metal grille.
Superbee - L100 Quadrex are $150/pair + $10 shipping.
It will probably be a couple of months before I begin construction. I'll let you know if I try your approach and need the foam. Thanks.
