Product Details
The QB1-XBD-A is a statement monitor that has no equal in terms of sheer power and resolution.

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.

Power is supplied by 1x Control 1200 and 4x Power 2400 ultra-low distortion rack-mountable amplifiers, providing HF 275W, MF 550W and LF 4x 2400W.
