Description

MSeries MB subwoofers are packed with advanced technology making them one of the most versatile, high-performance subwoofers on the market. The unique selectable impedance technology allows you to switch a single subwoofer between 2Ω and 4Ω via the included jumper cable. The highly advanced multi-voice coil and selectable terminal work in conjunction to produce a true 2" and 4Ω impedance unlike other selectable systems on the market. Memphis took cues from their flagship VIV1422 subwoofer to make the MB subwoofer a performance machine. The V-Groove surround allows for maximum excursion without sacrificing surface area and the DVVC Voice Coil Cooling technology pulls air out of the subwoofer much more efficiently than traditional pole venting. These subwoofers are built with performance and versatility in mind and will make the perfect solution for any audio system.
