R108

OVERVIEW
Montarbo R108: compact clarity, big impact. R108 is a compact, professional 2-way active loudspeaker designed for portable PA rental inventories and fixed installations where clarity, coverage and reliability are essential. Its bass-reflex architecture combines an 8" LF driver with 2" voice coil and a 1.35" HF compression driver, delivering balanced frequency detail. The system achieves a maximum sound pressure level of 125 dB, maintaining consistent intelligibility across small to medium audience areas. The loudspeaker's 90° × 70° coverage pattern provides wide, uniform horizontal dispersion with controlled vertical directivity, simplifying placement and reducing unwanted room interactions in acoustically challenging environments. This makes Montarbo R108 suitable for diverse applications including corporate A/V, mobile performance, DJ monitoring, educational spaces, worship facilities and distributed sound systems. Driven by a hybrid Class D + A/B amplifier platform rated at 200 W RMS / 400 W peak, R108 offers responsive transient performance and ample headroom for music and speech reinforcement. A dedicated cooling system with active fan management ensures thermal stability during continuous operation, while the onboard DSP employs FIR filters, 24-bit / 48 kHz conversion and 28/56-bit internal processing to refine crossover behavior, phase alignment and system linearity. Front-panel controls provide access to channel levels, preset selection and input sensitivity, while comprehensive connectivity-including Combo, XLR and 1/4" inputs with LINK/MIX routing and XLR line out-facilitates flexible system expansion, parallel feeds and simple multi-speaker setups for scalable configurations. Constructed from multilayer wood and protected by a durable polyurea finish, the enclosure is engineered for long-term robustness in portable and installed use. Measuring 264 × 440 × 260 mm and weighing 10.9 kg, R108 offers a compact footprint without compromising acoustic performance, making it a dependable choice for professionals seeking a versatile, high-fidelity loudspeaker solution embodying the unmistakable Montarbo sonic character.
