B108

OVERVIEW
Montarbo B108: discreet clarity for small installations. B108 is a professional 2-way active loudspeaker engineered for fixed audio installations requiring compact dimensions, controlled coverage, and high reproduction quality. Featuring an 8" low-frequency transducer with a 2" voice coil and a 1" high-frequency compression driver, the system provides a frequency response of 68 Hz-20 kHz and reaches a maximum SPL of 125 dB. A 90° × 60° dispersion pattern ensures consistent coverage in short-throw and distributed configurations. The Class D + A/B amplifier platform supplies 200 W RMS (400 W peak) of power and utilizes convection cooling for fanless, silent operation-ideal for conference rooms, educational spaces, and hospitality zones. DSP processing includes 28/56-bit internal resolution with 24-bit / 48 kHz AD/DA conversion and FIR filters for improved phase linearity, enhancing clarity for speech and background music. Connectivity includes a Combo input for CH1, XLR-F and 1/4" jack input for CH2, a 3.5 mm auxiliary mini-jack input, and an XLR-M line output for signal distribution in multi-speaker layouts. Bluetooth® 5.0 supports stereo wireless audio streaming for multimedia and BGM applications. User controls cover channel levels, main level, input sensitivity, preset selection, and LINK/MIX routing. Constructed from lightweight polypropylene, the cabinet measures 250 × 430 × 237 mm and weighs 8.5 kg-making Montarbo B108 practical for wall, ceiling, and pole-mounted installations while remaining suitable for small portable PA configurations.

APPLICATION
Montarbo B108 is well suited to small and medium-sized installation environments where speech clarity, musical detail, and discreet visual presence are essential. It integrates naturally into restaurants, cafés, retail spaces, classrooms, training rooms, and meeting facilities, as well as institutional and hospitality venues such as houses of worship, event spaces, visitor centers, and galleries-anywhere reliable reproduction and controlled coverage are required. Its onboard DSP and managed dispersion make it easy to deploy in distributed audio systems or in short-throw clusters for foreground reinforcement. And while B108 is primarily optimized for installation work, its compact form factor and modern connectivity also lend themselves to small portable PA setups, supporting presentations, rehearsals, and other mobile use cases with minimal effort.
