The Sonos Arc SL Shadow Edition is a Costco-exclusive premium soundbar that delivers immersive cinematic audio without built-in microphones, making it ideal for privacy-conscious listeners. Finished in a sleek shadow black color, its slim profile can be wall-mounted or placed on furniture, blending seamlessly into any home theater setup.

Featuring eleven high-performance drivers, the Arc SL produces crisp highs, dynamic midranges, and surprisingly deep bass from a single bar.

The soundbar was tuned with the assistance of Oscar-winning sound engineers to prioritize dialogue intelligibility, and a Speech Enhancement mode in the Sonos app can further clarify voices during intense scenes.

Setup is simple via HDMI eARC, and the Arc SL connects over Wi-Fi for streaming with Apple AirPlay 2 support. It integrates wirelessly into a larger Sonos ecosystem, allowing users to add surroundsound speakers for a full home theater experience. Dimensions are 44.95 in. W x 4.5 in. D x 3.43 in.
