Making our best even better is what our engineers accomplished for the newly redesigned 3XL Subwoofer Series. Combining a new bold look with the innovation that the 3XL series is known for, PowerBass created our most accomplished High Output Subwoofer to date. The 3XL series have beed designed to withstand the extreme heat that the new generation Class D Amplifiers create. Class D Amplifiers heat up the woofers voice coil two to three times hotter and faster than than a conventional class A/B amplifier. This calls for Xtreme measures and special parts to classify these as a true Class D Subwoofer. The 3XL 10" Subwoofers all feature 3" HD BASV voice coil formers high temperature voice coil winding to help dissipate heat. To allow full movement of the cone, we utilize an ultra high roll foam surround that increases the cone area for higher output along with linear cone stability throughout the subwoofers peak excursion.
