Power Acoustik GW3-10
10″ subwoofer · dual 2 Ω · 1,000 W RMS
Fs 35.3 HzQts 1.15Vas 1.07 ft³
The published specs don’t add up:
- Fs, Vas and Sd don't match the moving mass of 244.0387 g (they give 110 g) — one of the spec sheet values is probably wrong.
Recommended box
For a sedan, one sub, 1,000 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.

The spec sheet's Sd of 78.5 in² is the area of a 10″ circle, not the cone's radiating area — not used.
“≈” means the value isn’t in the spec sheet and a typical value for the size is used; “calc.” means it’s calculated from the published parameters. Check the manufacturer’s spec sheet before you build.
