NAMM 2024: Alcons Presents The M-series Pro-Ribbon Reference Monitor Series

Alcons Audio’s M-series is the group of reference monitor systems, to be used for critical sound reproduction in any application where ultimate analytical sound reproduction is required, combined with an exceptionally wide dynamic range. Designed with focus on the lowest distortion possible in every detail.

Ultra-low distortion 1:1 sound reproduction

By implementing Alcons’ pro-ribbon technology for mid and high frequencies, a very-fast impulse response with up-to-90% less distortion over traditional technologies is achieved. This enables the M-series to offer an intuitive linear response, non-compressed identical tonal balance at any SPL.

No listening fatigue

The superb transient response and the lack of “time-smear” results in the absence of listening fatigue. This maintains a stable, analytical 1:1 reference, even after prolonged listening sessions. It’s hearing instead of listening!

Wide sweet-spot with unsurpassed imaging

The pro-ribbon’s patented horizontal dispersion in combination with the constant directivity of the HempHorn™ and the optimized system phase response, offers a very wide sweet-spot and a perfect phantom image with ultra-wide and deep 3D localisation, up to and beyond 20kHz.

Seamless immersive experience


By utilizing the exact same 5” mid transducer with Active Coil™ and RBN202 high frequency driver throughout the complete series, M-series monitors can be mixed and matched for main and surround channels; This “identical voicing” delivers a seamless immersive spatial experience.

Virtually “infinite” headroom



The pro-ribbon’s 2” voice-coil has a power handling of 500W (200msec = 10x AES standard) and a 1:15 RMS-to-peak ratio; The ultra-robust multiple-patented pro-ribbon transducer technology provides a unique headroom reserve, reproducing even the most dynamic media without limitation.

Full-range down to 25Hz

The LF-section of the M-series monitors consists of next-gen transducers, featuring dual-coil motor structure with significantly-reduced distortion. The woofer is loaded by the new ScoopVent™ port, providing optimised flow without any port compression while extending the usable LF response down to 25Hz.

One reference; One experience.

Uniquely utilizing the exact same high resolution proprietary transducer, amplification and processing technologies from recording to mastering to playback and large-scale delivery, the Alcons systems offer one single, scalable cross-application audio reference: One reference; One experience.
