Reference I MkIII active sub bass system

The Reference I MkIII stands as a cornerstone of the MJ Acoustics range, engineered to provide the muscle and agility required for the most complex cinematic soundtracks and detailed musical passages. Despite its relatively compact footprint, this powerhouse consistently belies its stature, delivering a deep, immersive soundstage that transforms the home cinema experience. At its heart lies a 250mm ultra long-throw driver, housed within a critically damped, ported cabinet constructed from inert 18mm and 25mm MDF. This bass engine is powered by a high-current 250-watt MOSFET amplifier, ensuring that every transient is handled with surgical precision. By avoiding digital signal processing in favour of a pure, meticulously tuned analogue path, the system maintains perfect phase coherence with your main speakers. The Reference I MkIII is defined by its extensive controllability. Featuring an intuitive digital display and a comprehensive remote control system, users can fine-tune every parameter—including crossover, gain, and phase—from the listening position. With four user-definable presets, you can effortlessly switch between optimised configurations for film, music, or specific acoustic environments, ensuring optimal performance at all times.
