Joker Posted April 21, 2009 Report Share Posted April 21, 2009 (edited) Box is 6ft3 net * 32hz , 77.5sq inch port for a loaded 18" btl , sub up / port back , power is going to be a sundown 3500d * 1ohm . I was thinking of furthering the 45's to the top and bottom running horizontially{ very small peices not huge 45's like you see ) , not in the port though . More to get rid of as many 90 degree angles as I can . Do you guys think I should make the 45 on the port side bigger/wider ? Also thinking of putting a peice horizontally of sanded and rounded edged 3/4" mdf peice about 4" in length inside the middle of the 5" width port . Thought of making an extended peice that continues horizontially almost to the 45 since the area is wide open there . The top I have 2 peices cut so it is getting double baffled , sub will mount on second . Thinking 1/2" All thread making almost a cross inside the box mounted as close to middle as possible dodging the subs massive magnet . Maybe 2 peices of wooden dowel rod's running vertically on side of sub edge to help support the middle baffle area . I am going to try to mount the sub as far away from the internal port opening as possible . Here's some picture's of my box so far . Only my 2nd box I designed and built myself and I dont have a table saw or router , so take it easy .

Joker Posted April 21, 2009 Author Report Share Posted April 21, 2009 I didn't want to use 2x4 , they eat to much space and block the airflow. You have a wall , how about for just the common box .
