Where Can I Get Custom Made Foam for Speaker Box?

I bought a can of "Great Stuff" at Home Depot. It is a liquid that is sprayed out of an aerosol can. The liquid rapidly expands and then hardens. I used it to seal around some pipe openings in the garage wall -- just spray the stuff into the opening and it seals against insects and rodents.

Here's a video that gives an idea of how this stuff behaves:

It's available at other retailers, too, but here is Home Depot's page on it:

Why don't you just pack it real tight with bubble wrap or rolled up newspappers? What is your concern? If you pack tight speaker will not move.

you can buy 1" or 2" thick 4' x 8' panels of foam at Home Depot. You should be able to make one of these work.

I would use foam instead of bubble wrap...

good luck

+1 Philojet. The Great Stuff foam is EXTREMELY STICKY and it expands more than you think, even when warned. If it gets on the speaker, fughedaboudigt.

I use that spray foam often and will suggest to you, no warn you, not to use it. It gets on everything unless you are experienced with using it (even then it always seems to get on something). And like Swampwalker says, it always expands way more than you think. Yeah, even the low expansion version. If it gets on something, it WILL NOT come off.

Jameswei is got it right. I actually work with spray foam and here is my suggestion. First wrap/bag your speaker with plastic,place it in the box and then spray foam the gaps.The stuff expands a lot so don't use much,the only thing that cleans uncured foam is lacquer thinner.Be careful not to overspray on on surfaces thought,so do it outside.

Thanks, but I'll pass on the spray foam; way too troublesome.
