Calculating speaker enclosure volume is a five step procedure.
(Make sure you do not forget to subtract the thickness of the wood that you
have selected to use to build your enclosure.)
Complete formula should look like this
Height x Width x Depth / 1728 =__________
Below are illustrated versions of all the steps that you should take.
(FOR EXAMPLE ONLY)

Step Three
Step Two

13.5"
19.5"
13.5"
13.5-1.5+12
13.5-1.5=12
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.
Calculating thickness of wood:
Measure how thick the wood is then multiply by two.
The reason that you are multiplying by two is each
side of the enclosure.
Left + Right=1.5
Top + Bottom=1.5
Front + Back=1.5
1.5 cu. ft. is the results for this enclosure

Step One: Measure Height
Step Two: Measure Width
Step Three: Measure Depth
Step Four: Height x Width x Depth
Step Five: Divide the results that were in step four by 1728
12” x 12” x 12”= (1728 / 1728 = 1.0 cu ft.)
cu ft.
0.75 x 2=1.50
18 x 2 x 12=2592
2592 / 1728=1.5
