Box For My 6 8" Subwoofers
I'm thinking about making 2 ported boxes for my 6 8's, one on each side of the trunk, with the subs facing towards the middle of the trunk and the port firing at the backseat (see pic, like that but with the boxes parallel).
The recommended box volume is 0.75 ft^3 for a ported enclosure, so I figure make the boxes13x35x13 each, which equals 2.564 ft^3 = 2.35 ft^3 after sub displacement, which gives each sub 0.783 ft^3. What frequency should I tune the box to? The spec sheet for the MTX Terminators say they only get down to 40hz, but I'm guessing in the right box they will hit lower than that. I'm looking to maximize their low-end output. I want to make a port out of PVC pipe or something similar, just to keep things simple.
