Description.
The Montarbo Nettuno W12 is a professional 12-inch active stage monitor designed to give performers a clear, detailed sound they can rely on during live performances. Its two-way coaxial design combines a 12-inch woofer with a coaxially mounted neodymium compression driver, helping vocals and instruments remain focused and intelligible across the listening area. It is ideal for bands, touring productions, theatres, DJs and other applications where dependable on-stage monitoring is essential.
Powered by a 1,000W RMS Class D amplifier, the W12 reaches a maximum SPL of 136dB, providing the headroom needed for demanding stage environments. Its coaxial driver arrangement creates a coherent sound source, while the 90° x 90° dispersion pattern provides consistent coverage for performers. Integrated DSP with linear-phase FIR filtering helps maintain a controlled response, with eight selectable presets to suit different monitoring requirements.
Although designed primarily as a wedge monitor, the W12 can also be used vertically on a speaker stand, offering greater flexibility for side-fill and near-field applications. Balanced XLR input and link connections make integration with existing PA systems straightforward, while onboard sensitivity and preset controls allow quick adjustments. A USB-C service port is included for firmware updates and maintenance.
Built for the demands of professional live sound, the Nettuno W12 features a robust plywood cabinet with a durable black polyurea finish. Weighing 23.1kg, it includes integrated handles and a 36mm pole mount for easier transport and flexible positioning. For performers and sound engineers looking for a high-output 12-inch coaxial stage monitor with onboard DSP, the Montarbo Nettuno W12 offers reliable performance in a versatile, road-ready design.
One of the things we really like about the Montarbo Nettuno-W12 is its dedicated wedge monitor design, built to angle sound directly towards performers rather than out into the room. This makes it a practical choice for vocalists, musicians and DJs who need clear, consistent monitoring while performing. Its 12-inch configuration provides a capable full-range sound, while the compact wedge format keeps it neatly positioned on stage without getting in the way. For us, it's a great combination of thoughtful design, professional performance and everyday practicality.
