Reference 100 MkII active sub bass system
Precision sub-bass engineering for the discerning two-channel and cinema enthusiast.
The Reference 100 MkII stands as a testament to the idea that true sub-bass performance is measured by accuracy rather than sheer scale. As an integral member of the esteemed Reference line, it prioritises the preservation of the original signal, ensuring that low frequencies remain as agile and defined as the main speakers they support.
At its core, the design philosophy rejects the common use of digital signal processing, opting instead for a pure analogue path that eliminates latency and conversion-related degradation. This ensures a cohesive soundstage where the subwoofer does not merely add volume, but enhances the realism and spatial integrity of the entire system.
In practice, the Reference 100 MkII is remarkably fast, capturing the subtle textures of double bass or the tactile impact of orchestral percussion with ease. It is a disciplined performer, offering a controlled, musical presentation that remains unobtrusive until the demands of the recording require its presence.
Key Features
01
Pure Analogue Signal Path
The signal remains entirely analogue throughout the processing stage to avoid latency and ensure phase coherence.
02
Precision Crossover Control
Features a variable crossover with 1Hz increments between 20Hz and 120Hz for near-perfect system integration.
03
High-Level Neutrik Connection
The dedicated Neutrik Speakon input allows the subwoofer to receive the same signal as the main speakers for seamless sonic matching.
04
Remote Setup and Memory
Includes a remote control system to adjust gain, frequency, and phase from the listening position, with four user-definable presets.
Chapter 01
Engineering Philosophy
MJ Acoustics operates on the belief that a subwoofer should be an extension of the main speakers rather than an independent sound source. By utilising a sealed cabinet design and avoiding DSP, the Reference 100 MkII maintains the transient speed required to keep pace with high-fidelity monitors and floor-standers.
Chapter 02
Sonic Signature
The primary strength of the Reference 100 MkII is its lack of character. It avoids the heavy, sluggish overhang typical of mass-market subwoofers, providing instead a taut and tuneful foundation that adds depth and scale to a stereo image without drawing attention to its own physical presence.
