My friend is buyin a Fi Q with all the extras and we were wandering if any body had any old box dimensions and i dont want the dimensions from the website Q 15 – We recommend using a sealed box in the neighborhood of 2-2.6 cubic feet of volume. Ported box we recommend using 2.8-4 cubic feet @ 28-33Hz. Again use 12-16 square inches of vent area per cubic foot of volume. so plz if u have some dimensions for an 15" Fi Q ported box Thanks
