The published specs don’t add up:
- Sd of 160.3 in² is unusual for a 16″ (typically 102.3–145.7 in²).
- The published Xmax 1.34″ looks like max (mechanical) excursion, not linear: the excursion-limited power will read too high.
Recommended box
For a sedan, one sub, 2,500 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.
