PRO 80 MkI Active Sub Bass System
Authoritative sub-bass precision in a compact, hand-built 12-inch design.
The PRO 80 MkI represents a masterclass in efficient, high-performance sub-bass engineering. Designed to provide significant scale without dominating your listening room, this model distils the core MJ Acoustics philosophy of speed, accuracy, and depth into a compact, rigid enclosure that integrates effortlessly with any loudspeaker system.
At its heart lies a custom-engineered 12-inch ultra long-throw driver, powered by a 180-watt Class A/B MOSFET amplifier. This combination ensures that low-frequency transients are rendered with visceral slam and agility, entirely avoiding the sluggish, boomy overhang often associated with lesser compact subwoofers.
Connectivity is a hallmark of the PRO series, and the PRO 80 MkI excels with twin independent crossovers. This feature allows the user to simultaneously connect high-level signals from your stereo amplifier and low-level LFE signals from a cinema processor, with independent gain and filter settings for each. It is a configuration that transforms your soundstage, providing the deep, textured foundation necessary for truly immersive audio.

Chapter 01
Engineering Ethos
MJ Acoustics subwoofers are built on the belief that proper bass is the foundation for midrange realism. The PRO 80 MkI employs a sealed, hand-built cabinet that suppresses internal resonances, allowing the driver to operate with the agility required for high-fidelity music listening.
Chapter 02
On the Bench
The unit features a high-grade Class A/B MOSFET amplifier designed for rapid current delivery. By maintaining a pure analogue signal path and avoiding the latency of digital signal processing, the PRO 80 MkI preserves the phase coherence necessary for a seamless transition between your main speakers and the sub.
Chapter 03
Listening Notes
The PRO 80 MkI is celebrated for its musicality and pitch definition. It reveals the subtle textures of acoustic bass and the scale of orchestral works without ever drawing attention to its own physical presence, creating a cohesive soundstage that feels complete and authoritative.
