Recommended box
For a sedan, one sub, 2,000 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) | Dry and tight · 0.57 |
|---|---|
| Fc | 59 Hz |
| F3 (−3 dB, no cabin gain) | 78 Hz |
| Example box (outside) | 12 5/8″ × 12 5/8″ × 10 13/16″ |
Ported
deeper, louder| Tuning (Fb) | 38 Hz |
|---|---|
| Port | slot 1 15/16 × 14 5/16″, 57 1/4″ long |
| Port velocity at 2,000 W | 96 ft/s |
| F3 (−3 dB, no cabin gain) | 34 Hz |
| Example box (outside) | 31 1/2″ × 15 3/4″ × 9 5/8″ |
At 2,000 W this example’s port will be noisy: air speed 96 ft/s, while the limit is 82 ft/s. It stays quiet up to about 1,450 W. Full power needs a port of at least 33.1 in², which means a bigger box than this example — size it in the designer.
The volume and tuning are the recommendation, but the port doesn’t fit this example box. Size the box and port in the designer.
