16" H x 30" W x 24" D

4.5cuft @ 32.79Hz without the sub - Fi BL 15"sub displacement is .18cuft = 4.32cuft @ 33.xx Hz with the sub .

Little bigger than listed but I think this size is acceptable and will bang hard .

As you can see 4" slot port x 26" long = length to width ratio of 6.5:1

58sq in port area , 13.43sq in per cuft .

Cut sheet ~

Bottom - 24"d x 30"w

Back - 14.5"h x 30"w

Left side - 14.5"h x 23.25"d ( port side , drivers side )

Right side - 14.5"h x 22.5"d

Front - 14.5"h x 25.25"w

Port- 14.5"h x 18.5"d

Top- 24"d x 30"w

Final ~ 4.32cuft @ 33Hz displaced , 58sq in port area

Sub inside cut diameter = 14.125" .

so just cut the wood to that with mdf, and when it's together, those dimensions will give me around 33hz and around 4 cf3?
