ROUND PORT DIAMETER (IN)

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

MAX STRAIGHT RUN (IN)

MAX SLOT HEIGHT (IN)

The tool sizes the port for the target velocity, then checks whether the straight length fits. If it does not, it recommends a folded-port layout instead of pretending a long straight port will fit.

BAFFLE / OTHER DISPLACEMENT (FT³)

Enter clear internal dimensions. The builder subtracts the selected woofer displacement, calculated port displacement, and any extra displacement you enter for bracing or other internal parts. Use Build Me a Box below when you want the tool to solve dimensions for you.

MATERIAL THICKNESS (IN)

Uses the target net airspace, selected woofer displacement, the most recent port displacement, and your extra displacement to solve for the shallowest box using the maximum available width and height.

Folded Port Layout

PORT LAYOUT DIRECTION

PORT END MARGIN (IN)

V16 turns the calculated port into a real serpentine layout. It uses the selected slot dimensions, maximum straight run, and the box footprint when available. The drawing is a planning layout — final panel joints and end corrections still need to be verified before cutting.

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.
