> Worked sealed, vented and tapped-horn subwoofer examples with real simulation results and practical checks before a build.

Start with a real example, change one thing and read what happens. These recipes show how to make a design decision from the response and its limits.

## Pick a recipe

- [15 L sealed subwoofer](https://simulator.00aud.io/docs/cookbook/sealed-subwoofer): Swap the driver and power in a fixed-size box. Read bass output and cone travel together.
- [Vented 12-inch subwoofer](https://simulator.00aud.io/docs/cookbook/vented-subwoofer): Balance extension, port air speed and the space a longer duct needs.
- [Tapped horn subwoofer](https://simulator.00aud.io/docs/cookbook/tapped-horn): Increase drive and compare a high-pass filter before the driver runs out of travel below the horn’s working band.

## Use the results

- Each recipe states its driver, enclosure and listening conditions. Figures and quoted results come from the app’s solver.
- Change one variable at a time and keep the original design for comparison.
- Inspect the limits at the power you intend to use, including the frequencies below the useful band.
- Treat the example as a starting point. Check the driver data, physical dimensions and finished measurements before approving a build.
