Reference 800 Mk II active sub bass system

Uncompromising low-frequency authority for the most demanding high-end audio systems.

The Reference 800 Mk II sits at the apex of the Reference series, engineered to provide an unparalleled foundation for both two-channel music and high-resolution cinema. It achieves a rare balance of massive power and delicate nuance, ensuring that even the most complex low-frequency passages are reproduced with complete clarity. At the heart of the design is a robust long-throw driver powered by a high-current amplifier, encased in an extensively braced, hand-built cabinet. This combination allows the system to move significant volumes of air with effortless control, avoiding the sluggish overhang often found in lesser high-output subwoofers. Sonically, the Reference 800 Mk II is marked by its transparency. It does not merely reinforce the bottom end; it enhances the entire system, providing the weight, scale, and spatial cues necessary to create a truly believable listening experience, while remaining entirely composed under extreme dynamic demands.

Key Features

01

Chapter 01

Engineering Philosophy

MJ Acoustics operates on the principle that the subwoofer should act as a seamless extension of the main loudspeakers. By employing an analogue-only signal path and high-impedance high-level inputs, the Reference 800 Mk II tracks the signal sent to the main speakers exactly, ensuring perfect phase coherence and timing.

Chapter 02

Build Quality

The cabinet is constructed from heavy-duty, inert materials to provide a rigid foundation that resists unwanted vibration. Every structural component is chosen for its ability to manage high internal pressures, ensuring that the output remains clean and defined even at concert-level volumes.

Chapter 03

Sonic Signature

Expect a presentation that is both visceral and highly musical. The Reference 800 Mk II excels at revealing the delicate textures of a double bass or the immense scale of a cinematic explosion, all while maintaining the agility needed to stop and start instantaneously with the music.
