Question: what is a sonos beam?
Answer: Sonos Beam connects to your TV's HDMI-ARC port. Most TVs have two to four HDMI ports, one of which is labelled ARC, which stands for Audio Return Channel. ... While Sonos Beam is a great soundbar on its own, it also wirelessly pairs with our Sub for added bass and a pair of Sonos speakers for full surround sound.
