Deep, dynamic, bottom-end power is delivered by a pair of aluminium/paper/Kevlar® composite cone bass drive units. The 150mm Kevlar® midrange handles middle frequencies with its characteristic clarity and tunefulness, but, for the first time in a 600 Series speaker, includes FST cone surround technology for extra detail and resolution. The Nautilus™ tube-loaded, aluminium dome tweeter, featuring a new surround material to improve spaciousness and imaging, adds needle-sharp top end all the way to 50kHz and beyond.
The improvements to the drive units in the new 600 Series make it possible, for the first time, to introduce a minimalist crossover to the range. The use of components that are fewer in number but higher in quality – hand-picked in exhaustive listening tests – reduces the degradation of the signal significantly. So, whether you’re enjoying hi-fi or home cinema, what you hear is that much closer to what was recorded.
