Sonos Arc Ultra Dolby Atmos Soundbar Drops Back to a Record Low With Hundreds Off for Labor Day

The Sonos Arc Ultra Dolby Atmos soundbar is back at a record-low price for Labor Day, dropping to $899 from its usual $1,099 list price on Amazon. The review highlights its 9.1.4-channel design, delivered in a single bar using Sound Motion technology with high-excursion drivers to place audio above and around the listener without rear or ceiling speakers. Dolby Atmos decoding handles the overhead layer, while the AI-powered Speech Enhancement mode continuously boosts voice clarity. Setup is done via one HDMI eARC connection plus the Sonos app’s Trueplay calibration, which uses a phone microphone and takes about two minutes. Control is through TV remote via HDMI-CEC, the app, touch controls, or Alexa; music supports AirPlay 2, Spotify Connect and Bluetooth. Optional expansion includes Sonos Sub 4 and Era 300 surrounds.
