Description.
The Montarbo Nettuno L28 is a compact active line array speaker designed for professional live sound, touring and event production. Combining impressive output with flexible system configuration, it provides a scalable solution for sound engineers and rental companies working across venues ranging from theatres and concert halls to outdoor events and festivals.
At its core are two 8-inch ferrite woofers and a 1.4-inch neodymium compression driver with a 3-inch voice coil, powered by a 1,000W RMS Class D amplifier. With a maximum SPL of 135.5dB and 100° horizontal dispersion, the L28 provides powerful, consistent coverage while maintaining clarity across the listening area. Its symmetrical waveguide and phase-plug design help deliver a coherent response, making it well suited to demanding live performances and professional sound reinforcement.
Integrated DSP with linear-phase FIR filtering gives you control over system configuration without the need for external processing. Eight speaker-coupling presets help optimise performance when combining multiple cabinets, while eight high-frequency compensation presets allow the response to be adjusted for different throw distances. Up to 20 cabinets can be configured using the onboard rotary controls, making it easier to build a system suited to the venue and audience.
The Nettuno L28 features a robust plywood enclosure with a durable polyurea finish, designed to withstand the demands of regular professional use. Its integrated rigging system with locking pins supports secure flown configurations, while the built-in handles make handling and positioning more manageable. Pair it with the Nettuno S181 or S182 subwoofer to create a powerful, scalable PA system for larger productions. For professionals looking for a high-output active line array speaker with integrated DSP and flexible rigging, the Montarbo Nettuno L28 offers a versatile foundation for touring and fixed installations.
For us, the Montarbo Nettuno-L28 is an exciting option for anyone working in professional live sound. It's a powerful, compact line array that brings serious performance to touring productions, festivals and larger events without the bulk of some traditional systems. We particularly like how it combines high output with a relatively manageable format, making transport, rigging and deployment more practical for production teams. It's a well-considered professional line array that deserves a place on the radar of anyone looking to step up their live sound capabilities.
