'Gross' volume is the internal volume of the enclosure before the port volume is subtracted. If you're using external dimensions and you set the wood thickness to something other than '0', the wood thickness will be subtracted.
'Net' volume is the internal volume after the port volume is subtracted from the gross volume. If your speaker needs an enclosure that's 1.5 cubic feet ported at 35Hz, the 'net' volume must be 1.5 cubic feet for proper operation.
This is for PORTED enclosures.

  • If the angle is a negative number, 'depth 1' is greater than 'depth 2'. The face of the enclosure would be past vertical.
  • The angle at the top of the enclosure (inside) is 180-'box front angle'. If the BFA is 45 degrees, the top inside angle is 180-45 or 135 degrees.
