MB824

MB Subwoofers were designed with a goal of creating an extremely versatile subwoofer capable of producing intense bass response. MB subs were the first to receive Memphis’s patented Selectable Impedance Technology allowing you to switch between 2-ohm and 4-ohm on the fly. The MB824 was designed to provide audio fans with a subwoofer capable of being installed virtually anywhere. Whether you’re looking to build a custom system or upgrade your factory 8″ subwoofer, Memphis MB 8″ subs are a perfect solution.
