Blackedout Posted June 2, 2011 Report Posted June 2, 2011 Imo, I would do 3 4" aeros for the 2 sa12's. That comes up to being about 38sqin of port and if you are doing 2 cubes per woofer it is 9.5sqin of port per cuft. Imo 2 cubes is too much per woofer especially with a 3500d on the pair. I'd do something more like 1.5-1.7 per sub which would look more like this with 3 4" aeros: 3 cubes total= 12.66sqin per cube or 3.4 cubes total= 11.17sqin of port This is perfect. ~10 sq inch per cube w/ aeros, ~ 15 sq inch per cube with slot port.

zapme Posted March 20, 2012 Report Posted March 20, 2012 I believe 2 4" aeros is the same as a single 6" So whatever works better.. Id take a single 6" tho so prevents any sub from being closer to the port.. if u do a single 6",how long should it be.
