R115
R115 is a high-power, two-way active loudspeaker designed for portable PA systems, touring rigs, and mid-sized events. Its 15” low-frequency and 1.75” high-frequency drivers deliver powerful sound with extended bass, crisp mids, and defined highs. Thanks to its integrated DSP processor, it ensures a balanced tonal response, controlled dispersion, and reliable coverage. With versatile inputs and a rugged enclosure, the R115 offers professional sound reinforcement in a practical, portable design.
APPLICATION
R115 is ideal for portable PA systems, touring bands, DJs, and medium-sized live events where high SPL, clarity, and impact are required. Its extended low-frequency response, articulate mids, and focused high frequencies make it well-suited for music playback, live performance, and speech in small-to-medium venues, rehearsal spaces, and mobile setups.
Thanks to its flexible connectivity and scalable signal routing, R115 adapts seamlessly to different configurations—from stand-mounted mobile setups to multi-speaker front-of-house arrays. Built for touring durability and reliable performance, it provides professionals with a versatile, high-output solution for demanding portable and live sound reinforcement applications.
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 R115 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, R115 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.
