The box is built for 2 Sundown audio sa-12's tuned to about 35z with 2 2" ports  and i was wondering if those would be a big enough ports or if i should take out the middle separator and make it one big 3" port. The end goal is to have the least amount of port noise possible. This is with the 2 different ports   This is with the single port   And advice would be greatly appreciated.
