OVERVIEW
Nettuno W12: listen to yourself.
Nettuno W12 is an active two-way coaxial wedge monitor designed for professional stage applications, combining high output, clarity and controlled dispersion in a compact format. It features a 12″” ferrite woofer with a 3-inch voice coil and a coaxially mounted neodymium compression driver with a 1″” exit and 1.75″” voice coil. Powered by a Montarbo-designed 1000 W RMS amplifier with integrated DSP, W12 delivers up to 131 dB SPL with a frequency response extending from 50 Hz to 19 kHz (-10 dB).
The coaxial design ensures a coherent acoustic source, providing uniform response and precise intelligibility across the listening area, an essential requirement for stage monitoring. The DSP platform supports optimized system tuning and reliable performance in demanding live environments, while the robust plywood enclosure with polyurea coating guarantees durability for touring and rental use.
With its balanced output, compact footprint and focused sound projection, Nettuno W12 is ideal for live events, theatres, concert halls and houses of worship, offering performers a clear and powerful monitoring solution. Its versatility makes it equally suitable for portable setups and small PAs, delivering consistent results at every gig.

APPLICATION
The Nettuno W12 is designed for professional stage use, with a focus on reliable, high-performance monitoring. Its coaxial design and controlled dispersion provide clear, coherent sound for performers, making it an ideal wedge monitor for live bands, touring productions and theatrical stages. The W12 is equally effective for DJ monitoring, delivering punch and clarity at high levels while maintaining precise control in close-range listening positions.
In more complex live setups, the W12 can also be used as a side-fill or near-field monitor, supporting larger PA systems by reinforcing critical listening areas on stage. Built for mobility and rapid deployment, it adapts easily to different stage layouts and performance styles, offering consistent monitoring performance across live events, festivals and professional touring environments.
