So I decided to build my own box for the first time. The build took about 3 days or so, not the best, but, for my first box I'm happy with it. The enclosure is 4^ft3 net @38hz after .15 sub displacement , dimensions are 32x20.5x17, port is 4.5" in width, total port length of 24.75 and sq. port area of 69.75. Used only tb3 and like 40 1 5/8" coarse drywall screws, I know its a lot of screws but I can always remove them and fill in the holes i guess(no clamps:crap. Ended up not fitting in the trunk, building new one as we speak, but, I was able to get it in the back seat of my 94 century //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif, sounds amazing, especially with the sub inches from your ear, pushed some clean, loud lows. Just thought I'd share.
