(FOR EXAMPLE ONLY) Step One Step ThreeSide View 13.5" 7" 15" 15-1.5=13.5 Patent No: US D478,556 S Patent No: US 6,601,645 B1 Patent No: US 6,656,000 B2 23" 12" 21.5" 4" 4.5" Step Two 23-1.5=21.5 13.5" The wood that we are using is 0.75" thick The 1.5 that you see in the formula is the thickness of the wood. To calculate the thickness of the wood. Left + Right=1.5 Top + Bottom=1.5 Front + Back=1.5 .75 x 2=1.50 21.5 x 13.5 x 12=3483 3483 / 1728=2.01 2.01 cu. ft. is the result for this enclosure. Formula to calculate port displacement 3.14 x Radius x Radius x Depth= ________ / 1728=port displacement 3.14 x 2.25 x 2.25 x7=111.27 sq. in. 111.27 / 1728=.06 is the displacement of the port 2.01 - 0.06=1.95 cu.ft. is the final result for this enclosure. Patent No: US D478,556 S Patent No: US 6,601,645 B1 Patent No: US 6,656,000 B2 Circle Port Slot Port Converting a round port to a slot port. Calculate the area of the round port(s) being used, then use the square root function of your calculator to get the interior dimensions of an equivalent suare port. The length (or depth) of the slot port will be the same as that of the round port.
