PORT AREA (IN²)

SLOT WIDTH (IN)

SLOT HEIGHT (IN)

For a slot port, area = width × height. For a round port, area = π × diameter² ÷ 4.

MAX TARGET VELOCITY (FT/S)

PORT STYLE

Uses the selected driver's Sd and Xmax to choose a conservative minimum port area. For a slot port, the tool favors a practical 2:1 width-to-height starting point and then calculates the required length.

BAFFLE / OTHER DISPLACEMENT (FT³)

Enter clear internal dimensions. This first-pass builder subtracts the selected woofer displacement, calculated port displacement, and any extra displacement you enter for bracing or other internal parts.

Port Velocity Check

Sd (IN²)

XMAX (IN)

Worst-case peak flow estimate if the cone reaches Xmax at the tuning frequency. Use this as a conservative sizing check — it is not a prediction of actual operating port velocity.
