- Fs, Vas and Sd don't match the moving mass of 273.53 g (they give 372 g) — one of the spec sheet values is probably wrong.
Recommended box
For a sedan, one sub, 800 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 · 0.88 |
|---|---|
| Fc | 47 Hz |
| F3 (−3 dB, no cabin gain) | 41 Hz |
| Example box (outside) | 12 3/16″ × 12 3/16″ × 9 3/16″ |
Ported
deeper, louder| Tuning (Fb) | 42 Hz |
|---|---|
| Port | 2 round ports Ø2 1/2″, 17 5/8″ long |
| Port velocity at 800 W | 164 ft/s |
| F3 (−3 dB, no cabin gain) | 34 Hz |
| Example box (outside) | 20 5/16″ × 15 3/4″ × 7 11/16″ |
At 800 W this example’s port will be noisy: air speed 164 ft/s, while the limit is 82 ft/s. It stays quiet up to about 190 W. Full power needs a port of at least 20 in², which means a bigger box than this example — size it in the designer.
