MDF versus Baltic Birch?

I see that I missed this recent thread, although quite diversified on MDF / Plywood construction. Not to belabor this topic, due to construction costs and availability I was thinking about using Baltic Birch on the acoustic side of the enclosure and laminating with readily available MDF for rigidity. Pros / Cons? And while we're at it, any feelings on adhesive conposition? Thanks

Wow, great info guys. The MDF sheet that I have is the kind that can stay submerged in water w/o swelling (it's for use in the humid islands here and the supplier has had a sample piece in a 5 gal. pail of water for 2 yrs for display purposes). But even so, it sounds like biting the bullet and buying more Baltic for re-enforcement is the best way to go overall. Thanks to all

I'm presently at sea working on a ship, but as I recall it's called "Tight Bond". It's light brown in color and water based, very similar to Elmer's cabinet making glue but slightly higher on the food chain - unless someone can talk me into something different.......
