PMC QB1-XBD Main Monitors

To create the awesome QB1-XBD-A, we added a dedicated low-frequency cabinet to work in unison with the full-range main monitor. This additional 'XBD' cabinet contains four identical piston drivers, each driven by four of PMC's 1000w independent, class D power amplifiers, giving a staggering 8825W of ultra-clean power per channel.

The sense of limitless headroom and complete confidence gained when working on these is unparalleled from this twin-stacked cabinet design, and this configuration ensures the smoothest possible in-room bass response with 3dB more headroom than the QB1-A single cabinet version. Alongside its incredible power ratio and damping per channel, the QB1-XBD-A offers ultra-low distortion, a forensic sense of detail and incomparable dynamics and transience throughout the entire bandwidth.

In keeping with the QB1-A, the QB1-XBD-A features wired RJ45 desktop control, which provides user-friendly access to user EQ settings via its backlit display and jog wheel, and the ability to store up to four user setup presets.

Whether soffit-mounted or not, the QB models deliver the transparency, resolution, extended frequency response and wide, consistent imaging demanded by the international audio elite.
