This page is intended to demonstrate the incredible value of our 6 Year Supercare. Under recent legislation, we are obliged to point out that you obviously do not need to purchase an extended warranty at the same time you purchase your electrical goods and are entitled to shop around. We have been encouraging our customers to do just that for years because, not only are our prices significantly cheaper than our competitors, but just look at what else we include:

Free loan machine (only if taken back to store)
Should you encounter a problem, just ask and you'll be provided with a unit to ensure you're not without music whilst your equipment is being fixed.

Like for like machine if unit is unrepairable
If, for any reason, we are unable to repair your unit, we'll replace it. Naturally, models do change so, while we can't guarantee that it will be the same model, we do guarantee that it will have equivalent specifications.

Free routine service / Maintenance checks
have your unit serviced as often as you wish, free of charge, during the 6 year period. (Normally excluded from extended guarantees).

45 day cooling off period
If you're not happy with our 6 Year Supercare package just ask for a full refund - no questions asked. After 45 days, providing no claim has been made, you can also terminate the agreement and receive a pro-rata refund.

If you use the policy in the 6 years, you'll have saved yourself tens and perhaps hundreds of pounds. If you don't use it...IT WON'T COST YOU A THING!*

* Simply return your unused Supercare policy within one month of the expiration date, and we'll refund the price of your warranty.

"For such petite speakers, we were blown away by the big and confident output of sound." What Hi-Fi Sound & Vision magazine.


True to form, the Monitor Audio MASS satellite speakers are every bit the full-sized speaker scaled down. Rather than using inferior components, Monitor Audio uses its hi-fi quality drive units in this design. The C-CAM (Ceramic Coated Aluminium Magnesium) tweeter has an extended frequency response that stretches to 30 kHz. Whilst this may be well above our audible spectrum it does have a positive effect on the sound; lower notes that we can hear aren't compressed downwards or harmonically compromised. In short, the treble response is smooth, sweet and detailed. Matching this refined tweeter unit is a similarly impressive woofer. The highly developed C-CAM bass and mid-range integrates smoothly with the treble to give life-like vocals and a natural response. Another technically impressive feature is the woofer fixing. Rather than being bolted to the front baffle, through-bolt construction ensures isolation from the main cabinet and therefore a less coloured sound. The result of all this impressive technology is an exceptionally spacious and natural sound quality.


Providing power to match the control of the satellite speakers is an equally impressive subwoofer. Rather than using just one subwoofer unit, this sub uses two. One drive unit is actively powered while the other works in an ABR (Auxiliary Bass Reflex) role. This means added weight and depth of sound, without the requirement for a larger cabinet. Keeping these drive units in check is a hefty 220 watts, Class D amplifier, ensuring tight control of the bass at all times.


With their classy, silver-brushed aluminium caps, gloss back panel and wrap-around speaker grilles, the MASS satellite speakers make a smart addition to any home cinema system. The sub takes a similar shape and is comparatively slim and compact by subwoofer standards. Over all, this is a very unobtrusive 5.1 speaker system.

With class-leading sound and style, it's not hard to see why the Monitor Audio is the What Hi-Fi "Best style package £600 - £1000" product of the year.

Rated 5 out of 5 by Stunning! I purchased these over 12 months ago and, due to family issues, have only just managed to get them out of the box. I won't bore you with the details because many reviews here go into the specifics. All I will say is... I'm absolutely delighted with the quality of both sound and build. If you're looking for a discreet surround system then look no further! Having previously owned a Bose system and then a B&W system the pessimist in me expected a major drop in performance. Boy was I wrong! The Sub is quite large and very heavy. This shouldn't be seen as a negative... but if you have friends around please remind them that it's not a seat! Thoroughly delighted with my purchase and the service from Richer Sounds is second to none! Buy now! 15 September 2015
Rated 5 out of 5 Monitor Audio MASS 5.1 Speakers Fantastic value open box item; paired up with a Sony STRN1050 these speakers sound fantastic. This time I purchased some 14 guage speaker wire & even though it was cheap, it sounds awesome & was 20 GBP well spent. I recently purchased a pair of speaker stands & they complete the package. One of my best as well as cheapest purchases; A+ 14 September 2015
Rated 5 out of 5 by Amazing sound at a comfortable price The Monitor Audio Mass speakers really were a good buy; I purchased them with the Monitor Bronze 5 speakers to create 5.1 and I have not been disappointed. The only limitations of my setup are with my amp (I really wish I had gone for an amp that was compatible with 7.1.2 and had a separate 12v trigger). My setup is now amazing, and even the speakers without the sub knock-out some crystal clear, crisp and immersive sound. Excellent product if you love your movies, music and games. 22 August 2015
Rated 5 out of 5 by Excellant mid range speakers. They look good, sound good and by golly they are even better. Had to turn down the bass so powerful. Speakers did not distort at max volume (100 watts per channel), too loud for normal listening, lol. Watched my first DVD and when I left the room I realised the sound was so good it was like walking out of the cinema, now that's an experience. 25 July 2015
Rated 5 out of 5 by Great Speakers I have upgraded from my 5.1 system that i purchased from Richer Sounds, it was ok but i always felt it struggled a bit, since i purchased these i can only say the difference is incredible, the bass range is strong and vocals vibrant, it really does sound as good as the cinema, The large Bass speaker can handle all that you give, my AV Receiver, handles the sound well but i have set it up manually, this gives me what i am looking for, if you want a smile on your face, purchase these speakers, just make sure you have no neighbours. Highly Recommended. 05 July 2015
Rated 5 out of 5 A great step up I upgraded my Tannoy SFX with these, my room is around 4.5 x 4.5 meters so an average size room. I got them paired up with a Sony 1050 amp and used the LFE input on the sub. When using this the crossover is controlled by the amp so the crossover knob on the sub is redundant. I ran the setup routine using the amps mic and did some testing. The sub manual recommends setting the crossover to 80 but if found 90 was best as this gave more depth to the satellites especially with male voices. The difference between these and the Tannoy SFX is incredible. Watching my favourite blu-rays I can hear things I?ve never heard before, it really is cinema sound in your living room. There is so much clarity you will sit there mesmerised by what you are hearing. For a relatively small room the soundstage is huge! Even at low volumes you can hear every fine detail, with the Tannoy?s I was constantly adjusting the volume during night time movie watching but not anymore. 08 June 2015
Rated 5 out of 5 by Awesome So glad I now live in a detached house. The speakers really do look as good as they sound. I am running them through a Sony 1050 AV receiver combined the sound is amazing home cinema as it should be , and music rocks the house. I am one happy monitor mass owner. 22 April 2015
Rated 5 out of 5 by Outstanding The speaker size will make you feel how these small speakers going to fill the room, soon as you fire the amp you instantly realise the speakers are excellent for their size. The bass is very good and defined with the sub box that comes with the package. The sound filed is open and detailed, vocals are good. While listening to music the instruments sound extremely clear. I used to have the KEF egg shape for surrounds, you can hear the difference in the sound field, as how open and detailed it is compared to the KEF. The KEF are not bad speakers, don?t get me wrong, the Audio MASS just does things better. Driven by Pioneer LX77 AV Amp. 19 April 2015
