Sonos Arc Ultra

Sonos Arc Ultra – Sound beyond Surround

Sonos Arc Ultra is a groundbreaking premium soundbar that delivers ultra-immersive sound, extremely precise spatial audio, and crystal-clear dialogue in a sleek and elegant form factor. With all-new Sound Motion™ technology and Dolby Atmos, it creates a 9.1.4 sound experience that envelops you from all directions – without the need for external speakers.

The result is powerful home theater sound with greater depth, clearer voices, and more detail than ever before in a soundbar.

True 9.1.4 Experience with Dolby Atmos

The Arc Ultra precisely places sound around, beside, and above you. The upward-firing drivers create dedicated height channels that provide a three-dimensional sound field where effects move naturally through the room – perfect for movies, series, sports, and gaming.

(Requires compatible TV and Atmos content.)

Sound Motion™ – Revolutionary Bass in a Slim Form Factor

The all-new Sound Motion™ bass unit uses a quad-motor, dual-diaphragm design that delivers deep, controlled bass in a flat and compact form. You get powerful impact without the soundbar becoming larger or bulkier – and without the need for an external subwoofer (although a Sub can be added for maximum effect).

Ultra-Clear Dialogue – with Adjustable Speech Enhancement

With advanced Speech Enhancement, you get full control over dialogue clarity. Choose the level in the Sonos app and hear every word – even in low-volume scenes or intense action. This feature is particularly appreciated for news, movies, and TV series with complex audio mixes.

Arc Ultra is designed for modern homes:
