The PMC Loudspeakers 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.
