Each subwoofer unit is seriously over-engineered with generous headroom in all important areas. Components are hand picked and specifically designed into each system. MJ Acoustics unique combination of state-of-the-art electronis and tuned hand built cabinets, afford the user the ultimate in sub-bass control. Deep and powerful enough for the most demanding movie sound track, yet subtle, agile, fast, and accurate for the highest fidelity in music listening. Its just like beeing there!

Reference 210

The success of the Pro 100Mk2 cabinet design made the Reference 210 a natural progression. It takes an established platform and adds the missing link that projects the model into a world class Reference Grade Audio product and establishes itself at home underpinning the most accomplished audio system. It doesn’t matter whether it is a pair of small stand mount speakers in a 2 channel stereo system or largest of floor standers. All parts of this models have been specially designed to position the Reference 210 firmly in Reference Series line-up. New driver elements such as spider and coil, new main CPU motherboard and separate amplifier to handle the increased power delivered to the driver and ABR assembly are just some of the areas of development undertaken.

MJ Acoustics Pro 60 MK I Subwoofer
MJ Acoustics Pro 60 MK I Subwoofer
Pro 60 Mk1

When the Pro 50Mk3 was released there was only one observation from the design team when putting the final touches to this landmark model in the history of MJ. “will a larger version be even better?” Well, the answer is a resounding YES!! proportionally its the same diminutive size given the increase from 10″ to 12″ cone. So with the required tweaks in filter design to accommodate the natural roll off characteristic changes in the cone from the slightly increased mass together with larger internal cabinet volume, we established a magnetic structure and Gauss setting for the motor assembly that extracted the very most from this Bass Engine without the need to increase power by more than a few watts. The efficiency of the motor assembly was honed to perfection and the legendary Twin Crossovers installed to complete the design. Once again we set the standard for the most sound for pound you can achieve in a small cabinet.

Ref 100 Mk 4

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 has been increased significantly over previous versions.

Pro 100 Mk II

15 years ago the original Pro 100 was released with a resounding thumbs up from some of the most respected magazines in the industry. It was even used in the HiFi World Reference system to demonstrate Valve amplifiers.

“MJ LOVES TO MAKE Music” was the heading for a first tests review from What HiFi. 5 Stars and a verdict that said “Superb bass weight from what is still a very compact cabinet”

Pro 80 Mk1

When the Pro 50Mk3 was released there was only one observation from the design team when putting the final touches to this landmark model in the history of MJ. “will a larger version be even better?” Well, the answer was a resounding YES!! This gave rise to the release of the Pro 60Mk1 with larger cone area and larger cabinet. So how do you better this?

You take this platform and add the ability to make very accurate adjustments so that in multiple subwoofer systems you can properly tune them with repeatable settings that can be stored in non-volatile memory. You then push the boundaries as far as possible within the financial contraints of affordablity and extract the most output possible by tweaking the power available along with enhanced filters and crossover layout. All this achievable, because the microprocessor within the DAMP circuits monitors system status very carefully to make sure that the purest of output emanates from the cabinet without the slightest hint of distress or distortion in the waveform. It’s quite a marvel to listen to.
