Inverted Apex Surround

This super Car Audio Subwoofer features an Inverted Apex Surround that increases surface area and Xmax allowing for increased volume displacement and higher SPL as well as a progressive, layered spider that eliminates break in time and lowers distortion resulting in improved sound quality.

This subwoofer has a dual layer thermal management system that incorporates Spider Plateau Venting, a mechanical cooling process that targets cool air at the voice coil, and an integrated t-yoke heatsink that helps eliminate excess temperature for long term performance. The glass fiber cone offers excellent stiffness to weight ratio providing outstanding sensitivity.
