"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 Amazing sound and design. I've been looking for a good quality surround sound speaker system at a bargain price for sometime now and being the owners of two sets of monitor audio gold speakers was delighted when I happened across the Mass system at a reduced price. Being very careful in selecting the best at an affordable price reviewed and reviewed again until finally I decided to go ahead with the purchase. Setting them up with a Yamaha RXV 1073 receiver, Panasonic DMP BDP700 Blu ray player and 50" Panasonic HD TV I am truly ecstatic. The sound is huge with great detail in tweeter and mid range and very punchy in the base department and easily fills my 26 foot x 12 foot lounge. It's like being at the cinema. I highly recommend this product to anyone looking for a great speaker system. 02 January 2015
Rated 5 out of 5 by Awesome and now even cheaper Was totally unsure of which speaker package to go for 6 months ago but eventually chose these after advice from Richer Sounds Hanley who also convinced me to spend a bit more on a slightly better AV receiver as the manager recommended the Sony 1040 for my budget to get the best out of them. The sound can only be described as awesome and the sub can be controlled from relatively quiet to house shakingly loud and vocals are amazing for music and film and the satellite speakers are so small you have to hear to believe it. After seeing that these speakers have now come down even further in price if you are in the market for a new AV receiver and speakers around a grand then these cant be beaten in my opinion. Thanks for great advice. 21 November 2014
Rated 5 out of 5 by Fantastic product at this price point Had the speakers for 3 months sound great. Upgrade to my previous system, I thought long and hard as to wether it was worth while, it was. The speakers are detailed and controlled, filling the room with sound. Excellent with music and films. If your in the market for sub/sat speakers give these a try. Service from richer as good as always. Paired with the Sony1040 amp, a good sounding combination , good deal as bought as a bundle. 23 August 2014
Rated 5 out of 5 by FAB I have been on the look out for a replacement speaker system for some time, did all the usual demos including Bose, wanted something small but powerfull, having been imprested with the write ups and reviews went down to richard sounds for a listen. The rest is history, carnt get them on enough, dvd, t.v cd all sound great. Not as harsh as Bose as thats what i had before, sub gives better alround sound. sub is bit on the big side but the all the sides can be removed to reduce size, subs all have a brass nut in the back for fitting on stands, its a (whitworth thread ) which can be difficult to find , but a local nut n bolt company didnt have a problem supplying me with short bolts to suit. If u are lookling for a set up to shake the room but be refined when listening to all types of sound tracks or music you wont be disapointed.! 17 August 2014
Rated 5 out of 5 by Get these little yet powerful speakers I wanted power yet i also wanted small and discrete, these speakers are all this and more. The sub is massive but my god does it kick out some bass. Would definitely recommend, i hooked up a sony 1040 reciever no issues and great sound. I also added the bx5s as a 7.1 which has added a further dimension. You won't be disappointed if you get these. The staff were amazing and so helpful so if you do get these make sure it's from the Richer sounds experts. 10/10 17 August 2014
Rated 5 out of 5 by highly recommended highly loved I spent 6 months after I bought my Sony amp looking for the best speaker system for up 1000. Time and time again I was told consider the monitor audio system and time and time again I dismissed it. I visited amongst other shops 5 different richer sounds shops which didn't sit well with my other half. Without listening to the system I eventually conceded and followed the advise, didn't buy the q acoustics or other more expensive units and went with the monitor. Immediately impressed and even more after a couple of weeks of use. Now 6 months have passed I am still surprised at the warm balanced sounds on films such as star trek in to darkness followed by impact and depth of bass without any faults. I have now bought the matching stands for the rear which has finished the system off and could not be happier. Relentless comments about its looks and even more about the crisp sound and clarity of voice but some of that is thanks to the 840 amp. Really happy I finally bought both of these. 07 June 2014
Rated 5 out of 5 by Excellent... Absolutely loving this product, simply fantastic. If you are in a position to purchase this - DO IT! Rich, warm, balanced, smooth, punchy, etc... 27 July 2013
Rated 5 out of 5 by Great product I bought these thinking sat speakers are tidy, small and look great on the wall but these look expensive. my pals say get them on we want to hear these small speakers, The sound blown them away they could not believe the clarity sound crystal in there ears, in cinema mode the bass was unreal all coming together with the 200 watt base speaker and yes they all went home sick as a parrot because they want some. Overall a well priced product that I'm more then happy with go on treat yourself and get some. 30 May 2013
