[QUOTE="shredder2, post: 8701422, member: 674047"] To build one you can't use external dimensions without experience and understanding port area/tuning even if its given. Getting the portwalls dead-on takes knowledge. This is a 3 common wall sub/port on face trunkwalled design /w/ minimal materials for 2 Zvx-12's and a 4.5K wired down.

Consider power levels/vehicle/listening habits and you get a custom design. End-correction as well... it's all involved in being accurate, T/S parameters plugged into a modeling program on your power is the best way.
