MB1524 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 2Ω and 4Ω on the fly. This along with 4 sizes and a relatively compact profile make MB subs amazingly versatile and capable of performing in a number of applications.
