Internal air space after subtracting wall thickness, bracing, and driver displacement.

Speaker Box Volume Calculator | 2D Enclosure Drawings

How the speaker box volume calculator works

External dimensions, material thickness, and optional bracing or driver cutouts compute internal net volume. 2D drawings show front and side views for building rectangular speaker enclosures.

Key terms

Net volume (Vb) - internal air volume available to the driver.
Material deduction - wall thickness reduces usable space.
Bracing - internal structure that stiffens panels but reduces volume.
