Many British companies specializing in the production of subwoofers focus their attention not only (and not even so much) on the work of the bass module as part of a home theater system, but also on creating a serious low-frequency foundation when playing music. And MJ Acoustics Pro 100 one of the leading places among them is MJ Acoustics. MJ Acoustics is very proud of its British roots. The corporate website especially emphasizes that all employees of the company are British and that all production is concentrated on the shores of foggy Albion.

From the very beginning, MJ Acoustics specialized in the development and production of subwoofers. Perhaps this is because its founder and owner John Jefferis has an original view of what the ideal bass module for cinema and music should be. Over time, MJ Acoustics expanded its range with a complete set of acoustic systems for equipping a home theater XENO, as well as a floor and shelf model of the Subliminal AC. And yet, the company is most famous for its subwoofers, designed and manufactured in England.
The Pro 100 Mk II case is made of 18 mm MDF panels, and on the front wall, the thickness of the plate is an impressive 25 mm. The device is finished with natural ash veneer in black. Additionally, three more decors are offered from veneers of different types of wood, as well as nine ready-made color solutions. Upon request, the bass module can be made in any color from the RAL palette, which will be appreciated by interior designers. The quality of the finish is excellent. Since the subwoofer radiates downwards, it is mounted on high plastic supports with rubber pads. The kit includes both soft semi-circular legs and spikes.
For switching, there are both low-level inputs on RCA connectors and a high-level version made on a professional Neutrik Speakon connector (a cable of sufficient length with such a plug is included). In the English acoustic tradition, they prefer to create triphones for playing music using a high-level connection of the subwoofer directly to the acoustic terminals of the amplifier. The MJ Acoustics Pro 100 Mk II switching kit also has an LFE output for connecting several bass modules in a chain for a more uniform distribution of bass in high-class cinemas.

In addition, you can change the crossover frequency with an accuracy of 1 Hz and the signal phase with an accuracy of 1 degree. The remaining settings concern service functions such as the parameters of the power supply or display brightness. Of course, such a system is much more flexible than the usual way of commanding the subwoofer. The only thing to complain about here is the lack of auto-calibration for specific acoustic conditions and remote control, which are asking to be companions to the microprocessor control. And since we are talking about shortcomings, I will also mention the limited bit depth of the information display, due to which the system menu often uses abbreviations, and this complicates the setup – you have to repeatedly refer to the user manual.
The bass provided by the MJ Acoustics Pro 100 Mk II is surprisingly soft and comfortable. Such support of soundtracks from below does not bother at all, rather, it pacifies and soothes. Low-frequency waves seem to envelop the audience, gently touching and caressing them. At the same time, the device is capable of reaching real low-frequency depths. Of course, people who prefer it hotter may find that the transmission of hard shootouts and tectonic cataclysms lacks sharpness and pressure, but at the same time, this type of sound will certainly have many adherents. This manner will be especially appropriate when playing music. The subwoofer can create the necessary low-frequency foundation without rolling into a hum and distortion.
The amplitude-frequency characteristic of the MJ Acoustics Pro 100 Mk II subwoofer is quite stable and reveals a wide coverage area (Fig. 1). A smooth drop in the left part of the spectrum gives the estimated lower limit at 23 Hz. The upper limit of the passband can be selected using the built-in crossover at any point up to 130 Hz. The cutoff of the working area in the third octave of the bass range is quite correct and corresponds to the indicator readings. In the first two octaves, the set values begin to diverge from reality. Nonlinear distortions are extremely small at low and medium volumes. At a sound pressure level of 96 dB, a problem area is noted in the lower bass region (Fig. 2).
