Product Description

MJ Acoustics Reference 800 MkII Subwoofer merges cutting-edge electronics and versatile configuration while the closed cabinet design provides bass control parameters with superior flexibility.

Aesthetic Appeal

For a high-end visual appeal, elegant solid wood veneers are used while attention to the minutest detail in manufacturing quality ensures that the Reference Radial Series subwoofer outputs a fast, tight and deep low-frequency bass for LFE.

Low Frequencies

The low frequencies extend to a 10Hz/-3dB for the most immersive movie experience. Even for the most demanding movie soundtracks, its low-frequency depth and energy are powerful enough, whilst it still reproduces subtle, flexible, fast and high-definition bass requirements in a two-channel music listening system. The accuracy of the soundstage results in the scene as the director intended.


Built-in dual-precision crossover networks are freely adjustable between 20-120Hz. The rear panel of the cabinet provides a digital display and control buttons. Featuring a Smart Remote control system via Bluetooth BLE communication and an optional infrared remote handset and receiver eye, it is easy to recall four sets of user preset parameters. You can safely install any Home Theatre system with complete confidence.

Many ‘full-range’ loudspeakers cannot replicate the low bass frequencies found on most music and movie discs, these frequencies are essential for the precise reproduction of original recording to impart the lifelike ambience of a real-life recording. DVDs incorporate a dedicated bass channel for bass special effects, these being just as described, “special effects” to be precise LFE.

Bass Control

LFE should not be confused with the bass frequencies present in a normal full range sound signal being presented to the main full range speakers. A properly designed sub-bass system will not only reproduce these bass frequencies with accuracy but will also augment the output of conventional stereo music with very low-frequency bass. The result is greater audiophile fidelity in the lower and mid-band range.

Sub-bass system

The only way to add critical bass frequencies is via a well-designed sub-bass system which has the ability to reveal the deepest musical notes but also integrates seamlessly with loudspeakers so that your system speaks with a deeper, more natural voice.

There is nothing quite like the realism that results from adding an MJ Sub-bass speaker to your system; arguably a strong contender for title of the best 100% British Subwoofer available.

18" sub driver

Featuring a huge 460mm ultra long-throw super-rigid cast alloy radial driver, heavy-duty construction and elegant cabinet finish, the Reference 800 MkII delivers solid impact without the dreaded overhang down to 10Hz.

Affording ultimate control, this subwoofer fuses state-of-the-art electronics and tuned hand-built sealed cabinet. It has enough depth and power to tackle the most demanding movie soundtrack, yet is subtle, agile and precise enough for highest fidelity music listening.


For large installations requiring multiple subwoofers, the Smart Remote enables control of more than one subwoofer simultaneously for a seamless large room integration. Reference 800 MkII outputs serious SPL with Audiophile grip and control.

It is well-equipped and ready for most demanding movies and detailed bass lines. Made to special order, each subwoofer is assembled with the level of attention to detail that produces a stunning audio sculpture!
