As the smallest cabinet size available within the Reference Series, the bass output from this miniature power-house belies its size. Visually able to co-habit in the smallest of rooms it provides an audiophile option for underpinning the most acclaimed speakers of any size. REF100Mk4-SR enjoys the benefits of DAMP 3rd Generation along with matched component specification and meticulous build quality. The significance of DAMP 3rd generation cannot be stressed enough. Serious levels of computing and calculations are going on in the circuits of all Reference Series subwoofers. Monitoring circuits and control circuits all have to be managed and handled by the onboard processor. DAMP 3rd Generation relates to the faster processor and extended memory capabilities of the latest microprocessor that all Reference Series has installed. With the addition of Smart Remote for iOS and Android providing real-time communication between the user and multiple MJ subwoofers, the processor power and speed have been increased significantly over previous versions.
Each and every component is checked and measured against known specification and value so Reference components can be passed as within the design tolerance for the grade of Reference Series accreditation. We know how important each component’s tolerance can be within the audio chain and the tightest of tolerance makes a significant difference and qualifies for Reference grade Status.
This is an accomplished audiophile model with a long history of satisfied users around the world. We have added a host of additional features with this latest Mk4-SR version. An additional 4 rotary controls and 6 digit display is the obvious and immediate change visually. This, however, is just the beginning of the additional user features available with this most updated version.
Twin RCA inputs to enable augmentation of bass frequencies within an audiophile grade system from the line-level connection as well as the legendary High-Level input so unique to MJ Acoustics. RCA Input for LFE and RCA input for Centre channel connection. All inputs can be used simultaneously and we encourage you to do so when installing in a Home Theatre system. You can augment the bass for speakers connected to the Front Left & Right, Centre channel and the LFE source. A true enveloping soundstage can be achieved from a single subwoofer that makes all speakers in the system sound as though they are large floor-standers.
6 Inputs all at the same time! No other subwoofer can do this.
Additionally, power is increased from 120watts to 150watts. Launched back in 2002, it has been awarded multiple accolades evolving into an important part of the MJ Reference Series line-up. It is easy to set up and easy to position in the room and available in many different finishes.

The Reference 100Mk4-SR will prove to be the linchpin of your music setup.
Diminutive in size, Reference 100 Mk4-SR packs a punch equal to subs twice its size, yet it goes almost visually unnoticed due to its small 280mm square cabinet size. Loaded with a 250mm long-throw sub-bass driver, and tweaked High-Current power amplifier, the Reference 100 Mk4-SR is now better valued than ever before.
It even comes readily equipped for line-of-sight IR remote control and remote eye receiver option to make recalling one of the 4 user-presets an absolute breeze.
