You da man Q! One more question and I'll go back to quietly waiting Looking at absolute maximum dimensions, I could squeeze 450 sq in. (112/sub) but that would require a frigging shoehorn to mount everything. Do you think there could be a noticeable to the ear difference between 350 sq. in., 390 sq. in. , and 450 sq. in. of port at the same tuning? Is this even worth worrying about? This is a daily thing and not a chasing meter build.
