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.

Superior satellite speakers

The Monitor Audio MASS satellite speakers are every bit the full-sized speaker, just scaled down. Rather than using inferior components, Monitor Audio uses its hi-fi quality drive units, such as the C-CAM (Ceramic Coated Aluminium Magnesium) tweeter. This has an extended frequency response that stretches right up to 30 kHz, beyond human hearing. Lower notes in the audible range aren't compressed downwards or harmonically compromised, giving a treble response that's smooth, sweet and detailed.

Impressive woofer
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 hence a less coloured sound. The result of all this impressive technology is an exceptionally spacious and natural sound quality.

Powerful yet precise subwoofer
Providing power to match the control of the satellite speakers is an equally impressive subwoofer. This sub uses two units b one is actively powered, while the other works in an ABR (Auxiliary Bass Reflex) role. This gives added weight and depth of sound without needing a larger cabinet. It's powered by a 220W Class D amplifier, ensuring tight bass control at all times.

Sleek good looks
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 B#600 - B#1000" product of the year.

Rated 5 out of 5 by Fantastic set of speakers for the price! Got these speakers because they get nothing but good reviews on any website that sells them. Let me tell you they're not wrong the audio quality is exceptional you can hear the full spectrum of sound. It makes watching movies more cinema like. They look kinda funky too but be warned the sub is a beast! Also got to praise the staff at richer sounds Leeds they were really helpful and the service was great. Thanks 20 February 2016

Rated 5 out of 5 by Monitor Audio MASS 5.1 speakers Wasn't my first choice walking into the shop... Q Acoustics 7000i's were. Read lots of reviews before hand and due to space restrictions needed a slim speaker hence the QA's. Wanted good cinema as well as music capabilities. was able to listen to the MASS 5.1's in store and put them through their paces with both blue ray & cd's. Loved the detail they brought out in the film as well as the bass ability. Was pleasantly surprised by the music ability (thumping Faithless and some crisp acoustic) ; speakers are ported :-) Couldn't fault the sound for the money and made a great saving on the QA's. Bought a Denon AVR-X2200 receiver to go with them and the pairing is a face splitting smile. Great help and advice from Richer staff. 23 January 2016
Rated 5 out of 5 by For this price you cannot cry but shout about it. Just like being in the cinema. crisp clear and booming. 12 January 2016
