SONOS Arc Ultra Soundbar

Product Overview

The Sonos Arc Ultra soundbar is a premium home and commercial AV soundbar engineered for large display installations where high-fidelity audio and simple integration matter. Designed around Dolby Atmos 3D sound with upward-firing drivers, it delivers spatial audio that fills any room — from a private screening space to a dedicated conference room AV setup. As a wireless smart soundbar with HDMI eARC, the Arc Ultra connects directly to any compatible television or display with a single cable while supporting full network audio streaming. It is the right choice for AV integrators seeking a premium soundbar for commercial AV installation that demands minimal cabling and maximum audio performance.

Product Description

The Sonos Arc Ultra soundbar is powered by 11 Class-D digital amplifiers, each driving a dedicated speaker driver to produce full-range stereo and overhead audio from a single unit. Dolby Atmos support via upward-firing drivers creates a three-dimensional sound field without the need for rear satellite speakers, making it well-suited for conference rooms, executive offices, and high-end media rooms where a clean, minimal installation is preferred.

Connection is handled through a single HDMI eARC port, which passes both audio and control signals over the same cable used to connect to the display. This simplifies rack infrastructure and reduces the number of cable runs required during commercial AV installation. For network audio, the Arc Ultra supports Wi-Fi 802.11b/g/n on the 2.4 GHz band as well as a dedicated 10/100 Ethernet port, giving installers the choice of wired or wireless deployment on managed networks.

Apple AirPlay 2 is built in, enabling direct streaming from any Apple device on the same network without additional hardware or configuration. Voice control is supported through both Google Assistant and Amazon Alexa, allowing hands-free operation in spaces where that capability is appropriate. Capacitive touch controls on the top surface handle volume adjustment, play/pause, and track navigation without a remote. The Arc Ultra's auto-switching power supply accepts 100–240 VAC at 50–60 Hz, making it compatible with international deployments. At 44.95 inches wide and 3.43 inches tall, it fits naturally beneath virtually any large-format display while maintaining a low-profile commercial-grade appearance in matte black.
