General Info:
Model Name:B&W 683B&W CM9B&W 803 Diamond
Nationality:United KingdomUnited KingdomUnited Kingdom
About: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 three-way CM9 delivers truly commanding bass with the aid of twin 165mm paper/Kevlar® cone drive units. An FST® driver, with its characteristic compression surround supporting the outer edge of the distinctive Kevlar® cone, is specially developed for outstanding midrange performance. The CM9’s Nautilus™ tube-loaded aluminium dome tweeter keeps high frequencies crisp and sharp all the way up to 50kHz and beyond.The 803 Diamond might look almost as imposing as the 802 Diamond, but thanks to its smaller footprint and more traditional cabinet design, it will fit more comfortably into a home environment. With three massive 7” Rohacell® bass drivers, it delivers almost as much bass as the 802 Diamond, filling even the largest of domestic rooms with rich, stunningly lifelike sound. The design and proportions of the top two speakers in the range are derived at for sound acoustic reasons – but understandably, not everyone wants the visual disruption that such a radical piece of furniture can create in a home environment. The 803 Diamond takes up less space and is arguably easier on the eye – but thanks to its three bass drivers, it generates a sound that’s almost a match for its bigger brothers.
