RuarkAudio MRx Connected Wireless Speaker


As you would expect from Ruark, MRx is something rather special!
With great sound and a wide range of abilities, on its own MRx makes a perfect system for your lounge, kitchen or study, but linked with other MRx or our R5 and R7 Mk3 models it’s easy to build a wireless multi-room system for quality synchronised sound wherever required.


Streaming Heaven – MRx has been built for wireless streaming and offers a fantastic choice of options. For direct streaming, its Bluetooth receiver allows quick and easy connection and with aptX technology you will enjoy CD quality sound from compatible devices. With a broadband internet connection MRx comes alive and allows access to internet radio and an almost infinite library of music through online services such as Spotify, Deezer, Tidal and Amazon Music. Moreover you can also stream music stored on other networked computers and also from your phone.

High-Fidelity Performance – Specifically for MRx, we have developed new speaker units based on the driver technology from our award-winning MR1. A new cone and coil assembly coupled with the powerful neodymium magnet system provides a full-range driver with unrivaled performance. These drivers are mounted as a stereo pair into tuned bass reflex enclosures and powered by a high-fidelity two channel Class A-B amplifier. Using the latest sound processing technology, we have further tuned the sound and have created a stereo sound-stage that belies the MRx compact dimensions.

Easy to Control – Our stylish controller located on the front of MRx allows volume and source to be easily changed, but for full remote control we have a dedicated app for iOS and Android devices called UNDOK. This allows full control of all MRx functions and also displays information on the source material being played. UNDOK also allows users to create and manage groups when two or more MRx units are being used together as part of a multi-room system. R5 and R7 Mk3 are also compatible with MRx and can also be controlled with the UNDOK app.

Sychronised Sound – On its own MRx is a great music system, but with its ‘multi-room’ capabilities you can wirelessly link and sync MRx with additional MRx or our R5 and R7 MK3 models, so you can distribute music all around your home. Set-up and control is easy to perform on our UNDOK app for iOS and Android. This allows control of each device so volume etc. can be set just as you want it.
