Acoustic foam? You mean like that expanding insulation stuff, or do you mean sound-dampening foam sheets like Sonex?

I suggest you use polyfill like Acousta Stuff.

Ah, sure. You use it exactly like you would in a sealed enclosure, filling the space behind the woofer loosely with the fibers. The only difference in a ported enclosure is you want to keep the fibers away from the opening of the port, and of course none inside the port.
