Reference 400 MkI active sub bass system

The Reference 400 MkI represents a significant achievement in sub-bass reproduction, designed for listeners who refuse to compromise on speed or structural integrity. As a cornerstone of the Reference series, it delivers a sense of scale and visceral impact that remains entirely faithful to the source material. At its core, this model utilises a high-current amplifier coupled with a bespoke 300mm driver, housed within a cabinet engineered to suppress mechanical resonance. By eschewing digital signal processing, the system preserves the purity of the analogue waveform, ensuring that low frequencies are delivered without latency or phase distortion. Sonically, the unit is characterised by its disciplined presentation and transient agility. It uncovers textures within the lowest octaves that are often obscured by lesser designs, providing a seamless foundation that elevates both stereo music and large-scale cinematic soundtracks.
