The imposing 683 is the genuine three-way speaker of the 600 Series, with a line-up of technologies and a level of performance that defies its entry-level place in the market. For large rooms, two 683s make a formidable partnership, either for stereo hi-fi or fronting a home theatre installation. 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 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 683 to fit in effortlessly with any interior.
