i'm getting ready to completely gut my garage of anything that is not absolutely necessary. I'm tired of MDF dust on everything. I wish i could talk everyone into 13 ply baltic.....very nice work. Trust me you'll get sick of the dust when using a router to do the sub cut outs. It is the most accurate/easiest way, but do a few 18" cut outs in a row with a double baffle and your ENTIRE garage will be MDF dust...
