M-Series Studio Monitors

The M-Series was developed in collaboration with recording engineers and mastering specialists who demand absolute accuracy from their monitoring chain. Every element of the design serves a single goal: to reveal the truth in your audio without adding anything that is not there.

Each monitor houses a bi-amplified system with dedicated power stages for the low-frequency and high-frequency drivers. This eliminates the passive crossover entirely, allowing precise digital control over driver behaviour, phase alignment, and frequency response. The result is a seamless, time-coherent output from 38Hz to 35kHz.

Built-in DSP room correction analyses your acoustic environment and applies targeted compensation for boundary reflections, room modes, and desk-surface comb filtering. A three-band parametric EQ and high/low shelf filters give you further control to fine-tune the monitors to your specific mixing position. Whether you work in a treated control room or an improvised home studio, the M-Series adapts to deliver consistent, reliable sound.

Key Features

Flat Frequency Response

Engineered for neutrality, the M-Series maintains a ruler-flat response across its operating range, ensuring your mixes translate accurately to any playback system.

DSP Room Correction

An onboard DSP engine with included measurement microphone analyses your room acoustics and applies real-time corrections, compensating for reflections and standing waves.

Bi-Amplified Design

Separate 100W and 60W amplifiers for the woofer and tweeter respectively eliminate passive crossover losses and provide precise, active control over each driver.

AMT Tweeter

An Air Motion Transformer tweeter delivers ultra-fast transient response and detailed high-frequency reproduction with wide, even dispersion across the sweet spot.

Magnetically Shielded Cabinet

Full magnetic shielding allows safe placement near computer monitors and sensitive equipment without electromagnetic interference affecting your workflow.

Versatile Connectivity

Balanced XLR, balanced TRS, and unbalanced RCA inputs accommodate professional and consumer sources. AES/EBU digital input is available on the premium variant.

Frequently Asked Questions

Place the included measurement microphone at your listening position and connect it to the rear-panel mic input. Press the calibration button on the back of the monitor to start the automated sweep. The DSP analyses the room response and stores a correction profile that activates automatically on power-up. The entire process takes about two minutes per monitor and can be re-run whenever you change your room layout.
For most mixing and mastering tasks, the M-Series provides sufficient low-frequency extension down to 38Hz. If your work involves bass-heavy genres, film post-production, or immersive audio formats, adding a matched subwoofer can extend the system response below 25Hz. Our S-Sub pairs seamlessly with the M-Series via the dedicated sub-out on the rear panel.
The M-Series is designed as a near-field monitor and performs best at listening distances between 1 and 2.5 metres. At this range, direct sound from the drivers dominates over room reflections, giving you the most accurate representation of your mix. For mid-field applications in larger control rooms, contact us about our M-Series XL variant.
The M-Series is optimised for vertical orientation, which provides the widest horizontal dispersion and the most precise stereo imaging. While horizontal placement is possible, it can narrow the sweet spot and introduce comb filtering at the crossover frequency. If your setup requires horizontal mounting, we recommend angling the monitors inward and using the DSP EQ to compensate for any tonal differences.
