Uncompromising Vocal Performance
A House for High Frequencies
Every Three-Way Loudspeaker in The New 700 Series Has a Dedicated Midrange Cone Using Four Key Bowers & Wilkins Technologies: The Continuum Cone, Fst™, Biomimetic Suspension and Midrange Decoupling, the Latter Ensuring Minimal Interference from The Operation of The Loudspeaker’s Bass Drivers. Developed Using Advanced Computer Modeling Techniques, the Aerofoil™ Profile Bass Cone Has a Variable Thickness, Providing Stiffness and Rigidity Where It’s Needed Most. the Result: Deep and Dynamic Bass.
Sharper Detail
Carbon Dome Tweeters Are Purpose-Built for The 700 Series. Delivering a Dramatic Improvement on The Aluminium Double Dome Tweeter, They Raise the Breakup Threshold to 47k Hz, for Pinpoint Imaging Accuracy and Detail.
Truly Amazing Sound
Thanks to Its Composite Construction, the Continuum™ Cone Avoids the Abrupt Transitions in Behaviour that Can Impair the Performance of A Conventional Drive Unit. the Result Is a More Open, Neutral Performance that Delivers Voices and Instruments with Precision and Transparency.
