[QUOTE="BOOMINGRANDPA, post: 8653897, member: 671921"] box looks to be 1.85 or so cf BUT that doesn't count port or sub displacement.. if port is about 2" wide x 13.5" high x 13' deep that would be .2 cf and whatever sub disp is so like .15 = 1.50 cf ad at best and port would be tuned way to high man.. u really need 2cf ad ported tuned lower (35 hz) so over all box would be like 9" wide and squared back 15 deep and tall.. port size dpend on how much power u have to it too though but that box just really ain't right..
