Default waterproofing speaker backs - Water stop foam?

I'm just buying the parts to replace the factory fit loudspeakers. Will be buying some 4mm Silent coat sheets for the inside of the door skins but I can't find any waterproof acoustically transparent foam sheets (called water stop?) for the backs of the speakers, to protect them.

Any ideas?

Thanks, Ali.

But I don't see why you need them on a 75 / ZT - there's already a water sheild between the door and the speaker and door card.

Yes, speaker baffles. Thanks, but not what I'm looking for. They're not acoustically transparent. so called 'baffles' just create a sealed box with very little internal volume and would ruin the bass response.

The water shield on the doors will be cut behind the speaker thereby using the internal volume of the door to create a better bass response. As I've said, the inside of the outer door skin will be lined with 4mm Silent coat.

What I'm looking for is some nice acoustically transparent (open cell?) foam which is also waterproof.

Ali.
