NETTUNO L28

OVERVIEW
Montarbo L28: 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.
