Bose's newest collection of home audio devices adopts a modular approach to the home theatre setup. The Bose Lifestyle Collection includes the Lifestyle Ultra Speaker, Lifestyle Ultra Soundbar and Lifestyle Ultra Subwoofer. These products all support Google Cast and Apple AirPlay and can be used as a single setup or in multiple rooms. As ZDNet noted, though, they do not offer backward compatibility to older Bose devices. At most, you can wire the Bose Bass Module 700 to the Lifestyle Ultra Soundbar.
