Posted this earlier in a different subforum. Found this section and this seems a better place for this. Sundown Audio website recommended enclosure for X12 dual 4 v2 Ported 2.5^3 Displacement .2 Tuning 32hz Port Area 40^2 I was thinking that the 2.5 cubes is NET, but then I opened the box spec/cut sheet and see the recommended box size is 20x20x15.5. That is more like 2.77 gross. Now I built that 20x20x15.5 and while building it, I noticed the port was way undersized (2"x14") so I made the port area wider by 3/4" (to get it closer to the 40sqin) which made the NET cubes 1.7^3 tuned to 40hz with 38.5 sqin port. This box sounds awesome with some songs with the sub up/port back but should definitely be tuned a bit lower to suit my needs. I have to keep the port at least 8 inches away from the trunk wall, any closer it looses sound and rattles the heck out of my rear door. Problem is that it doesnt fit in my Scion xB without the seat folded down so I need to build another enclosure. Can someone recommend a net size for this woofer? If I have that, I can go from there. Any help is very appreciated. I will be giving this woofer the rated power plus some.
