Sonos Arc Ultra Soundbar — Black
The Sonos Arc Ultra is a mains-powered home cinema soundbar finished in matte black. It connects to a compatible television through HDMI eARC or ARC and supports Dolby Atmos with suitable content and equipment. Sonos describes its spatial presentation as a 9.1.4 experience; this does not mean a separate subwoofer and rear speakers are included. Sound Motion technology provides bass from a compact woofer design, while Speech Enhancement and Night Sound offer different ways to manage dialogue and changes in programme volume. Wi-Fi, Apple AirPlay 2 and Bluetooth support music playback beyond television viewing. The Sonos app provides setup, adjustable bass and treble, and Trueplay room tuning on compatible iOS and Android devices. Bluetooth playback does not replace the internet connection needed for initial setup and connected functions. A single HDMI TV connection is provided rather than multiple HDMI source inputs, so other video equipment connects through the television. Optional compatible Sonos rear speakers and a subwoofer can expand the system later. Those extras and any wall bracket are separate purchases; this listing is the black soundbar only.
