ACV SW PRO102D
10″ subwoofer · dual 2 Ω · 500 W RMS
Fs 30 HzQts 0.33Vas 0.71 ft³Xmax 0.75″
The published specs don’t add up:
- Fs, Vas and Sd don't match the moving mass of 133 g (they give 230 g) — one of the spec sheet values is probably wrong.
Recommended box
For a sedan, one sub, 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.
