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.
