Fixing down a portable subwoofer

And screwing into the subwoofer won't cause an airleak or make a problem?

Looks like the sides of that box are wood. Assuming you don't take the screw out the screw fills the hole it makes so it shouldn't leak any air If you're worried, use screws shorter than the depth of the wood.
