Posted June 4, 201312 yr I just ordered (2) FI SSD and I'm wondering how big I should go on the box. I want to get the most I can out of the subs. They will be powered by my sundown SAZ 2500d. The biggest dimensions I would like to go are: 44w x 36d x 25h. The 36d gives me about 7 inches from the hatch door. The FI website calls for 3-4 cubes a piece at 33 hz. How big do you think I should go? What tuning frequency? Any help is appreciated.
June 4, 201312 yr Model the subs. You have a flatter responce at lower volume. Larger the volume with the same tuning will result in a ripple around tuning then turning saddle shaped up to the cut off frequency of the sub. If you want more output. Go up to the largest box that will fit while keeping ripple no more than 3db and keeping delay less than 28 m/s below ~30 hertz.
June 4, 201312 yr Author Too vague...What additional information do you need?Model the subs. You have a flatter responce at lower volume.

Go up to the largest box that will fit while keeping ripple no more than 3db and keeping delay less than 28 m/s below ~30 hertz.So just got the full 8 cubes?
June 4, 201312 yr Author What is ripple? i'm not building the box i'm having someone else do it but I have to tell him how I want it
June 4, 201312 yr Ripple is a ripple or wave in the responce. A positive ripple will provide more output.
