Recommended box
For a sedan, one sub, 700 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) | Tight and punchy · 0.80 |
|---|---|
| Fc | 51 Hz |
| F3 (−3 dB, no cabin gain) | 48 Hz |

Ported

|---|---|
| Port | 2 round ports Ø2 1/2″, 17 13/16″ long |
| Port velocity at 700 W | 130 ft/s |
| F3 (−3 dB, no cabin gain) | 36 Hz |
| Example box (outside) | 19 15/16″ × 15 3/4″ × 8 1/4″ |
At 700 W this example’s port will be noisy: air speed 130 ft/s, while the limit is 82 ft/s. It stays quiet up to about 270 W. Full power needs a port of at least 15.8 in², which means a bigger box than this example — size it in the designer.
