Default Reticulated Foam Speaker Grill

Does anyone know where I can get white reticulated foam suitable for making a speaker grill? The stuff used in pond filters appears suitable but I need it at least 450mm x 1100mm. It's for an IB subwoofer. Thanks.

Thought I had found something, but it's out of stock! What thickness are you looking for?

You also have to consider the PPI which stands for pores per inch.

A foam with 10PPI will offer very little restriction to air flow whereas a 60PPI is sure to restrict the air flow.

Thanks for looking, where was that, I'm not in a hurry? An inch would be fine, I don't want it too thick.

Forget my first find! It was 255 for a 2" thick, 1500 x 2000mm, sheet!

I found this set of PPI images, said to be approximately full scale.

I wanted something self supporting but it may be simpler and cheaper to use cloth on a frame, thanks for looking anyway and the info.
