Calculating a sealed speaker enclosure volume is a six step process.
Step One:
Measure Height
Step Two:
Measure Width
Step Three:
Measure Depth
Step Four:
Subtract Thickness of Wood
Step Five:
Multiply Height * Width * Depth =
Step Six:
Divide the results from step four by 1728
EXAMPLE: 12" * 12" * 12" / 1728 = 1.0 cu. ft.
Complete formula should look like this
Height * Width * Depth / 1728 =_____________
Below are illustrated versions of steps to calculate the enclosure volume.
(ILLUSTRATED EXAMPLE ONLY)
If measured internal dimensions you will skip step four.
Step Two:
(Width) 18"
Step Three:
(Depth) 13.5"
Side View
12"
13.5"
18"
19.5"
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.
Step Four:
Calculating thickness of wood:
Measure how thick the wood is then
multiply by 2.
The reason that you are multiplying
by 2 is each side of the enclosure.
Width 19.5" - Left + Right(1.5") = 18"
Height 13.5 - Top + Bottom(1.5") = 12"
Depth 13.5" - Front + Back(1.5") = 12"
Step Five:
Step Six:
Step One:
(Height) 13.5"
13.5"
12"
18 * 12 * 12 = 2592
2592 / 1728 = 1.50 cu. ft.
