Posted August 5, 201114 yr so i need the calculations needed to figure out my problem(or the answers) with this build want it to be a true not done on a online cal.(unless one will give true port cal within a 2hz of needed frequency) box 20h*48*40*d using 6in PVC? thanks to all that have any input for me. its 4 15s and want to tune between 30 to 34hz.
August 13, 201114 yr You have to give more info. How thick is the box going to be? How much space is used by bracing and the subs? A rough estimate is 19-20". I used 12.5 cf as the box size.
