12" Single Voice Coil Subwoofer with stacked 40oz magnets delivers low distortion bass that pounds in either sealed or vented enclosures.
High-gloss-finish polypropylene woofer cones – Polypropylene, a lightweight and popular material, is used to ensure maximum woofer efficiency. The benefit is high output with modest amplifier power.
Large-roll rubber surrounds – Rubber provides optimum cone-edge suspension and absorbs distortions that may travel up the cone edge, ensuring clean, tight bass.
Vented polepieces – Provide additional cooling of the motor. The subwoofer's thermal capablities are augmented, thus increasing power handling.
