Im making a box for 2 12'' v-Max's tomarrow and i want to build a snail shell, does anyone have enough time to draw up some dimensions for me, or a web site would be great also. Would this work good, or should i just make a ported box, or should i go with a round or slot port? The dimensions have to fit between 18 high, 19 deep, and 36 wide, thankx for the help!!!
