B&W Bowers & Wilkins Speaker รุ่น 705 S2 Rosenut

This uncompromising two-way speaker reveals subtle nuances in music others miss. Its high performance features include a solid body tweeter-on-top design borrowed from the 800 Series Diamond.

Solid Body tweeter
Milled from a solid block of aluminium, the solid body tweeter housing design creates an acoustically optimised housing for the tweeter – one that’s exceptionally inert and resistant to resonances.

Carbon Dome™ tweeter
Carbon Dome™ tweeters are a brand new technology purpose-built for the 700 Series. Delivering a dramatic improvement on the aluminium double-dome tweeter, they raise the breakup threshold to 47kHz, for pinpoint imaging accuracy and detail.

Continuum™ cone
First introduced with the 800 Series Diamond, the Continuum™ cone represents the biggest step-change in midrange performance since Kevlar®. Its woven, coated material provides highly controlled break-up, resulting in a more open, neutral midrange.
