Pride LP 10 D2
10″ subwoofer · dual 2 Ω · 450 W RMS
Fs 38.2 HzQts 0.50Vas 0.64 ft³Xmax 0.63″
The published specs don’t add up:
- Xmax is rated at 50% BL drop — more than the usual linear Xmax; the excursion headroom will read too high.
Recommended box
For a sedan, one sub, 450 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.

Qes and Qms are not on the spec sheet — calculated from Qts, motor strength BL and Re.
“≈” 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.
