[QUOTE="SHiZNiLTi, post: 2932495, member: 561248"] So u probably want sub up port back right? The box that I built for the BTL was loud but didnt bring out the lows around the 30-32hz range that well. It tended to sound the best at the 36-40hz range, those notes sounded great and got very loud at that range. Maybee try using flared aero ports. Have you ever considered that? I would do sub up and ports firing to the side, I bet you get some good sq with this setup. (6) 4" aero ports @ 22" long will get your 7cuft box (37x22x24) tuned at 34hz with 75sq.in. of port area.
