I've been considering building speakers and subs with two layers of MDF, and a layer of cork between them.
However, I found out that cork expands and contracts with small water exposure (fear: humidity).
And I want to give my projects a mirror finish, so I can't have it expanding and cracking my auto paint/clear.
Is there another material that I can use, in the place of cork?
And because this isn't a speaker building forum, I will explain the purpose of cork: It's a dissimilar material, compared to MDF. It's softer, and resonates at a lower(?) frequency.
That should reduce the noise that gets 'out' of the box.
