hey guys,

im looking for port design suggestions for an enclosure that is 31.5" wide x 18.25" deep x 15.5" high ID. looking overall to be slot ported out of the side @33 and want to keep 12-15 square inches of port area per cubic foot. port dimensions i'm coming up with are 15.5"w 3" high 22" long. thanks for any input!

what is the displacement of the driver(s)? your box, before driver displacement, comes out to 3.24 net, and the port is 14.35sq/cu tuned to 37.4hz. i can run the numbers back and forth some more, but it will be better to go off the specific driver t/s parameters and displacement, first...
