OVERVIEW
adaptive nature in a lightweight enclosure.
Nettuno L28 incorporates two 8-inch ferrite woofers and a 1.4-inch neodymium compression driver with a 3-inch voice coil, powered by a Montarbo-engineered 1000 W RMS amplifier featuring integrated DSP and FIR filtering. Its symmetrical waveguide and phase-plug architecture deliver exceptional efficiency, achieving an optimal balance of compact form factor, refined industrial design, and impressive acoustic output.
Deployment is streamlined and intuitive: up to 20 cabinets can be configured using only two rotary encoders, with coupling and HFC presets readily accessible. With a 100° horizontal dispersion, the L28 ensures smooth, uniform coverage across wide or acoustically challenging medium-size environments. External processing is unnecessary—the built-in high-frequency compensation provides precise control over each cabinet’s throw, enabling effortless system optimization.
When paired with the Nettuno S181 or S182 subwoofers, the L28 forms a coherent and scalable system capable of delivering focused energy and consistent performance for audiences of up to 5,000 people.
The modular architecture ensures controlled vertical directivity and wide, even horizontal dispersion, enabling precise audience coverage and minimizing unwanted reflections in complex acoustic environments. The active subwoofer module provides deep, impactful bass extension suitable for music reinforcement, live events and outdoor productions, allowing Nettuno 50 to operate as a scalable front-of-house solution for medium-to-large venues, festivals and touring stages.
Powered by a high-efficiency amplifier platform with advanced 32-bit DSP management, Nettuno 50 offers precise system tuning, high headroom and fault-safe operation through active protection stages including peak, RMS and thermal limiting. Integrated presets optimize deployment for stacked, flown and hybrid configurations, while RDNet connectivity ensures streamlined control, monitoring and system diagnostics across multi-cabinet setups.
Touring-grade plywood enclosures, professional rigging and suspension hardware and robust mechanical design make Montarbo Nettuno 50 suitable for intensive rental, touring and installation environments. Whether deployed as a standalone system or integrated into larger PA architectures, Nettuno 50 delivers the unmistakable Montarbo sound with power, definition and reliability for high-demand professional sound reinforcement.
