The XB2 is a passive sub bass unit that is best optimized in an MB2 surround monitoring system. The line design and driver technology are identical to that of the MB2 and MB2-A, forming a perfect blend of dynamics and depth of bass required for the most testing of material. The unique 12" Radial™ driver features two cooling systems.

In addition to the conventional rear vented magnet it uses the patented, front mounted Radial™ chassis, which acts as a giant heatsink. This keeps voice coil and magnet temperatures exceptionally low resulting in superb reliability, 3dB less power compression and tight, clean bass even after prolonged periods of high SPL.
