The soundbar, logically called the Formation Bar, contains three 25mm tweeters and six 65mm woofers for bass and mid-range sound. On the music side, it supports Bluetooth, Spotify Connect, Apple's AirPlay 2 standard and Roon, an audio player that combines Tidal and locally stored files with media-rich metadata. Film lovers, meanwhile, get Dolby Digital and a few basic ports including Toslink optical-in. Notably, the Bar doesn't have a HDMI slot and, therefore, can't use your TV's HDMI-ARC port.
Bowers & Wilkins calls the Formation Duo, a pair of bookshelf or stand-mount speakers, its "concept car." They look and sound like the company's classic wired speakers, such as the 705 S2 and 805 D3. Each Duo has an isolated tweeter on top and a larger bass and mid-range woofer in the center, which uses the company's special Continuum-branded cone design.
