Note: This is the Gross internal volume of air. To get Net volume for tuning, subtract the volume displaced by the subwoofer driver (usually 2-5L) and any ports/bracing.
Overview
Speaker box calculation determines enclosure volume for optimal sound. Sealed vs ported designs. Based on speaker Thiele-Small parameters. Essential for custom audio builds.

Pro Tips
Sealed: tighter bass, smaller box.
Ported: louder bass, larger box.
Internal bracing reduces resonance.
Polyfill increases apparent volume.

Fun Facts
"Subwoofer box: 1-2 cubic feet typical."
"Bookshelf speaker: 0.5-1 cubic foot."
"MDF preferred over particle board."
"Qtc = 0.707 for sealed alignment."
Formula: Volume = Length × Width × Height (internal); Port tuning depends on volume
