Im wondering what most of you are using between the two layers of wood. I am thinking of making the baffle out of two sheets of mdf and am not sure what to use between them. I used to use a glue that Northcreek used to sell for this purpose because it wouldn't harden like wood glue, thus soaking up vibrations from the wood. Also wood there be a significant gain in doing this or am I doing more work than needed. Project is a slim 2-way with 36x8x10 with a vertical brace from top to bottom of enclosure. 3/4" mdf on all walls and brace.
