AV Forums

MASS 5.1

September 2014

"It sounds bigger than it actually is."

AV Forums tried Mass out, and asked "Can this unusually styled set of speakers take the fight to the category champions?"

Well, with a shiny 'AV Forums Recommended' award, it would appear that MASS certainly can! "MASS manages the most important achievement of any sub/sat system - it sounds bigger than it actually is." 

"The use of identical satellites means that the handover from speaker to speaker is seamless and this further aids the sense of being in the thick of the action. The reproduction of fine detail is extremely convincing and like its larger brethren, the MASS achieves this without needing to drive the bolts out of it - although you can push it fairly hard without it hardening up."

5 Stars for Mass from BBC Music Magazine

"The power produced by the diminutive satellite speakers is nothing short of breathtaking-this level of sound seems to have no business emanating from a system of this size...This is, pound for pound, one of the finest 5.1 systems I have across and one that is equally at home with music as it is with full movie surround."

Sound & Vision Magazine: MASS Test Report

Sound & Vision magazine has examined Monitor Audio's own MASS 5.1 speaker package in a detailed Test Report. Esteemed reviewer Al Griffin gave his opinion of the system:

"Monitor Audio has distilled the know-how that informs its higher-end speaker lines into a compact speaker package aimed at home theater newbies, I can't help but envy them."

"With MASS, not only will they get a full 5.1 system at an affordable price, but...the experience is sure to exceed their expectations"

MASS Review in Home Cinema Choice Magazine

Mark Craven, editor of Home Cinema Choice magazine, is not one to hand over awards lightly. He’s seduced however by the MASS package: perfectly formed and priced, and complete with a mule’s kick in the bass department. He says “put into action with film soundtracks, the MASS system simply shines…the sound is crisp, detailed and utterly immersive. Overall, Monitor Audio’s newest product lineup is the perfect partner for a mid-range AVR in a living room cinema setup. Everything from the build quality and design to movie and (sub assisted) music performance impresses.”

What Hi-Fi? Sound and Vision

MASS 5.1

October 2012

Small system, big sound, massive achievement.

It shouldn’t be possible for such room-filling sound to come from so space-friendly a system – yet it does! The experts at What Hi-Fi? have experienced a few unlikely outcomes in their time, but nothing as downright astonishing as the performance of our latest miracle of precision engineering: the highly bijou MASS AV system. And they’ve taken it to their hearts, awarding it five stars and price-class winner at this year’s What Hi-Fi? Awards. The team says:  

'What struck us immediately was the sense of scale and power - for such petite speakers, we were blown away by the big and confident output of sound. And they’re certainly capable of filling a decent-sized room as well; our testing rooms were engulfed in seamless, controlled soaring dynamics.'
