B & W 684 Speakers
|
The extended bass response and output capacity of the 2½-way 684 floorstander make it a great choice for hi-fi or home cinema in medium-sized to large rooms.
It features a new combination of a pair of Kevlar® cones for delivering its bass and midrange. The lower cone is dedicated to bass, which relieves the upper bass/midrange unit of the duty to handle heavy bass and leads to clearer, crisper midrange than you might find in smaller speakers. 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.
Visually, a refreshed, contemporary design language and a widened choice of wood finishes allows the 684 to fit in effortlessly with any interior.
