Lumber for horn housing

I'm making a housing for a composite horn. The 10" driver will be in a small (barely bigger than the driver) enclosure, and I'm building a larger box to protect the horn and allow stacking and a pile mount (it's for events not home audio).


It will deal with a lot of SPL, but I was hoping/guessing that since none of the enclosure will serve as a resonant chamber, and I'm not going below 200hz With it, I don't need to buy specialized wood (void free Baltic birch vs Home Depot sanded ply).
that's my thought, but we all know what they say about assuming thing!

oh, and speaking of NOT resonating, any recommendations on what to use to dampen the box around the horn? Ideally something light.
 
Thinking that not going with quality plywood as a cost saving measure is short-sighted.

What kind of format of horn were you thinking, there is more than one way to build them. and some suit some materials better than others.

Althou given the necessary mouth size to reach 200 Hz, and the need to pack it around, it is likely going to be folded.

It's a COMPOSITE horn, 17" deep and 21 wide 14" tall. That includes a flange. So the wood is just a housing to protect it.
