"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.

MONITOR AUDIO MASS 5.1 is rated 4.9 out of 5 by 41.
Rated 4 out of 5 by from I am loving it It's been not a long time with this product, I purchased this Monitor Audio Mass package with Yamaha AV receiver and I am LOVIN it. the Sound stage is very spacious, the effects are really realistic. The bass doesn't overcome the sound and is there when you need it only. Really nice. Ofcourse no product is perfect, could have done with wireless speakers, but then again it would have come at a price, so very satisfied with this, bang on for the money.

Rated 5 out of 5 by from Truly Awesome! I have had surround sound separates for quite a number of years but have just upgraded my speakers from Canton Movie CX85s with canton bookshelf L/R. Having bought these refurbished from Richer Sounds at £300 (yes, just £300!), I am astounded by the difference that it has made to my system and I am now truly getting the performance my Denon X2200 is capable of... especially with the new firmware update with DTS:X I simply recommend them at any price. They are beautiful in design and incredible in audio output for movies and music too. Still using the Canton bookshelf L/R but will change these to Mass 10s when I can find a pair at the right price.

Rated 4 out of 5 by from The audio quality is very good I love the design and build quality of the surround speakers. The subwoofer performs extremely well but I wish it wasn't quite so bulky.

Rated 5 out of 5 by from Speaker design has a real modern look This system has real character and sounds fab. Richer sounds were un beatable for price and service. There are more expensive systems out there with a less than impressive impact.

Rated 5 out of 5 by from Room filling sound This speaker set really packs a punch. The satellite units are well designed and look great on their tailor made stands. The sub woofer is large but again well designed, so does not look out of place. It's performance is outstanding and the cross over from the small speakers is seamless. The only negative is on the assembly of the stands which requires an amount of patience and thought. Teamed with the Denon 2300 av amp. Very pleased with my purchase.

Rated 5 out of 5 by from Blow you away sound excellence ! These speakers are absolutely amazing. Firstly the design and excellent build quality are just great. Then to top that the sound is sensational at all volume levels. The detail and sharpness is so clear and precise. The base tones are equally responsive and deep. If you want to get the best sound experience then buy these speakers and I would also recommend the Yamaha RX-V681 AV Amp as I have them set up with this and can say 100% sounds fantastic. Enjoy every time I watch a movie or listen to my music library, never fails to disappoint.

Rated 5 out of 5 by from Don't even hesitate! I genuinely cannot fault these speakers. They were a breeze to wire up and the instructions were clear and easy to follow at each stage. When paired with a good quality amplifier, these speakers effortlessly fill any standard sized living room, and I would bet even bigger rooms besides. My biggest concern with new speakers was having them blend in nicely, or at least compliment the furnishings of the room. With a clean, incredibly high quality fit and finish, non-intrusive size and modern but not crazy aesthetics, I can safely say it meets my requirements. The photos do not do them justice, I highly recommend seeing (and hearing) them for yourself. The sub woofer is fairly hefty and has roughly square dimensions, so take that into account when deciding it's placement. Don't let it's size scare you though, it's only as loud as you make it and provides silky smooth bass response even on the lowest of volumes.

Rated 5 out of 5 by from stunning sound quality I purchased the system in the New Year sale. Martin (manager) at the Solihull store was really helpful. I cannot say enough about the quality of this speaker system,the detail and clarity of the sound is fantastic, the sub is a monster but with careful setup integrates really well with the sat speakers.Movies come alive and music reproduction is top notch for this type of speaker system. I'm over the moon with my purchase and recommend the product highly,
