R115

OVERVIEW
Montarbo R115. High-output versatility R115 is a professional 2-way active loudspeaker engineered for high-output portable PA, touring, and medium-sized live events. Its bass-reflex architecture combines a 15" low-frequency driver with 3" voice coil and a 1.75" HF compression driver, delivering extended low-end authority, clear midrange, and detailed high frequencies. The system reaches a maximum sound pressure level of 132 dB, ensuring intelligibility and dynamic impact across demanding performance environments. The loudspeaker's 90° × 40° coverage pattern provides wide horizontal dispersion with controlled vertical directivity, enabling precise audience coverage and minimizing unwanted reflections. This makes ideal for mobile PA systems, front-of-house setups, stage monitoring, touring, and rehearsal spaces. Powered by a Class D amplifier platform rated at 600 W RMS / 1200 W peak, delivers responsive transient performance with ample headroom. Its passive radiator design ensures efficient low-frequency extension without the need for active cooling. Onboard DSP processing-including FIR filters, 24-bit / 48 kHz conversion, and 28/56-bit internal processing-optimizes crossover behavior, phase alignment, and overall tonal balance. Front-panel controls offer channel-level adjustment, preset selection, input sensitivity, and LINK/MIX routing, while comprehensive connectivity-including Combo, XLR, and 1/4" inputs with XLR line output-enables flexible multi-speaker deployment and scalable system expansion. Constructed from multilayer wood with a protective polyurea coating, the cabinet is engineered for touring durability. Measuring 427 × 705 × 428 mm and weighing 25.9 kg, R115 combines high output and extended bandwidth with reliability and practicality for professional portable and live performance use.
