The Bowers and Wilkins Formation Duo are a pair of active bookshelf speakers which are part of Bowers and Wilkins' Formation range of wireless speakers. These are the powerhouse speakers of the Formation range, coming in a pair these will fill any room thanks to the 124 watts of power coming from each speaker. The design is pure Bowers and Wilkins, the protruding tweeter-on-top using the same carbon dome design as many other speakers from Bowers and Wilkins. The Duos have more engineering cues from other B&W products, the Continuum cone from the 800 Series Diamond has been used in these speakers. With a weaved synthetic material similar to Kevlar, the Continuum cone is stiffer though and therefore provides more self-damping. As a Formation speaker pair, these will integrate seamlessly with the rest of your Formation speakers and uses the same hi-res sound technology as all the other speakers. These are a real treat for fans of the Formation series and for those looking for a good stereo pair of speakers.
