Since the beginnings of ‘Hi-Fi’ over fifty years ago, it has been known that loudspeaker cabinet resonance is a major factor limiting a hi-fi system’s sonic performance. Fortunately it is very easy to overcome; you simply have to spend a very large amount of money designing and constructing heavy, dense, high mass cabinets with lots of internal bracing. The result should be excellent, but very expensive, ‘high end’ loudspeakers. In fact the difference between speakers that are rated merely as ‘good’ and those accepted to be truly excellent ‘high end’ models, is their level of cabinet resonance. Q Acoustics Concept Series changes everything.
