Featuring a second cabinet devoted exclusively to bass, with an additional single 12-inch Radial bass driver, the twin-cabinet MB3 XBD-A system offers still better dynamics than the MB3, with an additional 3dB of headroom below the bass crossover frequency of 380Hz, and allows larger rooms to be driven with an even smoother frequency response, producing a maximum SPL of 129dB. The twin XBD cabinets can be freestanding or soffit-mounted, and may be positioned vertically or side by side for greater flexibility. As with the MB3-A, a matching low-profile centre channel (MB3 XBD-C-A) is available for use in multi-channel arrays. Thanks to the wide-ranging frequency response of the twin-cabinet system, additional dedicated subwoofers are not a requirement.
