Formula:

Gross Box Volume = (((H-(T*2)) × (W-(T*2)) × ((A-(T*2)) + (C-(T*2)) )) / 2) /1728 Net Box Volume =Gross Box Volume - Speaker Displacement Box Front Angle =tan-1(((H-(T*2))/((C-(T*2))-(A-(T*2))))) Where, H = Height W = Width A = Depth1 C = Depth2 T = Wood Thickness

Example:

Find gross box volume and net box volume of triangular speaker enclosure. Its have 100 inch height, 50 inch width, 20 inch depth1, 30 inch depth2,2 inch wood thickness and 9 ft3 Speaker displacement.

Solution:

Gross Box Volume = ( (100-(2*2)) × (50-(2*2)) ×(( (20-(2*2))+(30-(2*2)))/2)) / 1728
=((100-4)*(50-4)*(((20-4)+(30-4))/2))/1728
=(96*46*42/2)/1728
=53.6667 ft3

Net Box Volume =53.6667 - 9
=44.6667 ft3

Box Front Angle=Math.atan(((100-(2*2))/((30-(2*2))-(20-(2*2)))))
= Math.atan((100-4)/((30-4)-(20-4))
= tan-1(96/10)
= 84.0531 °

Triangular speaker enclosure volume calculator calculates gross box volume, net box volume in different measurements such as mm3, cm3, cl, l and so on. Box front angle in either radian or degree as you wish.
