Create a full surround sound system with this B&H Kit that includes the Yamaha MusicCast BAR 400 Soundbar System and a pair of white Yamaha MusicCast 20 Wireless Speakers. They connect to each other wirelessly, or to your network via Ethernet, and can be programmed to work together as a 5.1-channel surround system or multi-room audio system via the MusicCast Controller app. You can also use your Amazon Alexa device enabled with the Smart Home and MusicCast skills to link the speakers and soundbar system together, play music, and more.
