Anyone see any problems/ improvements with this design? I am going to add 45's in the corners, just didn't draw them in. Dimensions are 49w 17D 27H. For 2 AQ SDC2.5 15's.
Put dowels going from the sides to the port walls, and put a couple of 45's where the port splits...it'll add bracing to the back wall, which you need, and it'll improve air flow through the port. And be sure to rounover those interior port corners.
