## The problem

Fitting a subwoofer box into an odd-shaped space — a car boot, a cabinet — usually means cardboard mock-ups, guesswork and wasted plywood.

## How it's built

- Upload an STL or OBJ scan; it's parsed and repaired in the browser and never leaves your machine.
- Calibrate scale, level the floor, close the cavity and mark keep-out zones.
- Pick a driver from the database; target volume, tuning and port length come from its Thiele-Small parameters.
- A deterministic solver finds the biggest rectangular, convex or non-convex box that respects every build constraint.
- Exports nested DXF and SVG, a cut list with bevel angles, 1:1 templates, STL, bill of materials and cost.

## What it does

- < 60 s typical solve
- ±1 mm verified fit
- 28 drivers in the database
- 6 export formats
