Ok guys The sdc2.5 I have now is loud but not enough. I designed a box today in sketchup that would be forward firing and sealed off with two havoc 12s on a soundqubed 2200d. Box is 6.12 Gross 5.16 Net tuned to 34.92hz with 2 6 inch aeros that are 18 inches long each. This gives me 10.95 per foot of port. WIll this work well?

I would center the ports. That really bothers me for some reason, it'll probably work fine though.

How close are the ports to the back wall?

good catch on the port and back wall. I can change it to double 5 inch aeros that are 14 inches long and it will put the port 6 inches off the wall and tune it to 31.81hz

agree that box is a bit big for 12s 4-5 cubes is more then enough bigger box power handling goes down and plays sloppy
