Recommended box
For a sedan, one sub, 900 W. It’s the same math as the designer’s step-by-step mode, where you can fit the box to your space, vehicle and amp and get plans, a cut sheet and DXF.
Sealed
smaller, tighter| Bass character (Qtc) | Flat and accurate · 0.76 |
|---|---|
| Fc | 50 Hz |
| F3 (−3 dB, no cabin gain) | 49 Hz |
| Example box (outside) | 12 5/8″ × 12 5/8″ × 8 7/8″ |
Ported
deeper, louder| Tuning (Fb) | 45 Hz |
|---|---|
| Port | 2 round ports Ø2 1/2″, 15 1/8″ long |
| Port velocity at 900 W | 169 ft/s |
| F3 (−3 dB, no cabin gain) | 38 Hz |
| Example box (outside) | 16 5/8″ × 15 3/4″ × 8 7/8″ |
At 900 W this example’s port will be noisy: air speed 169 ft/s, while the limit is 82 ft/s. It stays quiet up to about 210 W. Full power needs a port of at least 20.6 in², which means a bigger box than this example — size it in the designer.
