MJ Acoustics
MJ Acoustics founded by John Jefferis was created to pursue an ideal, namely the reproduction of the most natural sounding, true to life bass possible with current technology, but at a price that favours both the wealthy and not-so-wealthy enthusiast. 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!

All of this produces a subwoofer to engender pride for MJ Acoustics as a British Manufacturer, and for you the Customer.

Best of all its a 100% British product made by a 100% British company in Britain!
MJ Acoustics Reference 100 MK II Subwoofer
MJ Acoustics Reference 100 MK II Subwoofer
The diminutive Reference 100 MkII packs a punch equal to subs twice its size, yet it goes almost visually unnoticed due to its small 278mm square cabinet size. Now with a 250mm long-throw sub bass driver, a 10 metre high level cable, and M8 spikes, the Reference 100 MkII is better value than ever before. If thats not enough, it even comes with a totally out-of-sight remote control and a remote eye receiver to make recalling one of the 4 user-presets an absolute breeze. Ask your local dealer for a demonstration today and experience the missing link to your system!
