Kicker 50CVX152 CompVX 15-Inch Subwoofer, Dual 2-Ohm

High-temp dual voice coils deliver the power, while a solid pole piece provides more mass to subdue additional heat. A T-cut top plate creates a wider magnetic field for stronger bass response, and better sound. It all comes together to form a super-reliable motor structure found only in a KICKER subwoofer.
