Posted December 19, 200717 yr I need box plans for a Fi Q12 (dual 2). It going to be powered by a Sundown 1000D. I want it to get loud but also have SQ. So Im thinking tuning it to 32hz. Fi recommends 12-16 square inches of vent area per cubic foot of volume. The demensions I want to use are 14.5 H, 28 W, 18 D. (can change alittle)
December 19, 200717 yr This box will work great that I posted. Make it 28" wide and 14.5" tall - depth is still 18 and the rear port wall is still 10" long. Makes 2.3 ft^3 tuned to 32-33 Hz.Brian Edited December 19, 200717 yr by BKOLFO4
December 19, 200717 yr Ported box we recommend using 1.8-2.5 cubic feet @ 28-33Hz (I personally think that a 32hz tuning is optimal, and has the most output and is still the most musical daily driving). Use 12-16 square inches of vent area per cubic foot of volume.For a 12", yes.
