Specs:
Memphis 4KW - currently wired to 1.8 ohms for sub break in
Two DD9515's - dual 1.8's - fresh recones
Two Kinetik HC2400's
I built an enclosure that measures 58" wide, 17.5" tall, and 23" deep with a double baffle, and 132 sq. inches of port. The box is just over 8.5 cubes after displacement. The port measures 16" tall x 8.25" wide, and 16.5" long. All corners are 45'd.
I am having issues with port noise and output. Since the port is in the middle of the enclosure, and is 16.5" long, there is 4.25" of depth at the end of the port on each side to the rear of the enclosure. I am getting a severe vibrating noise which I am assuming is port noise. It seems to be at higher frequencies, and dissipate at lower frequencies. You guys have any ideas? Also, the output seems to be extremely low.
Here's the pics of the enclosure:
