[QUOTE="squidlover, post: 4690818, member: 595452"] I figured out the box size I think. I came up with roughly (internal) 21.25x13.75x14.5 = 2.2. I then subtracted the sub displacement .071 and got 2.1 cubic ft rounded off. I figured out the slotted port length at 28.8'' at 33hz tuned To get the vent displacement I did as follows- 28.8x14.5x0.75= 313cubic inches the 28.8 is the vent length- 14.5 is the internal height and the 0.75 is the mdf thickness. I'm not 100% positive this is how to get the vent displacement but it seemed to work. I then added that volume 313 cubic inches to the box and got 2.4 cubic ft. My new dimensions to keep the box tuned to 33hz after the vent displacement are as follows, internal measurments 22.5x12.5x14.5 = 2.39 cubic ft rounded up. Is this correct? I Friggin hope it is. I never did this much math in my life. Someone, anyone please shed some lite on this subject. Thank You Squidlover [/QUOTE]
