The bass-reflex cabinet is equipped with a 15” woofer and a 1.35 ”compression driver boosted by a 1200 W Class D amp module.

B series’ advanced DSP featuring FIR filters allows a smooth audio performance as well as an impressive dimension/sound pressure level up to 130 dB.

B series speakers feature 3 input channels (Mic/line, Line, Bluetooth) with independent levels. Bluetooth devices can be easily connected thanks to the on-board “PAIR” button.

Moreover, 4 different on-board presets allows users to optimize the audio performance for the application in use.

A clean design integrates 3 handles and rigging points for fixed installation to the lightweight polypropylene cabinet which also allows horizontal stage monitor use, thanks to a 40° inclination of 2 sides of the box (a dedicated preset wedge EQ is selectable on board). The flange for pole fixing on the bottom of the box allows users to choose a 0° or a 7.5° inclination of the cabinet placed on a standard 35 mm tripod.

Covers for transport and weather protection are available as accessories for every model in Montarbo B series.
