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.
