Experience Cinema-Quality Sound with Sonos Arc Ultra

The Sonos Arc Ultra is a soundbar with Sonos' first-of-its-kind Sound Motion transducer technology. It offers a transformative audio experience in a sleek, modern design that fits seamlessly into any home theater setup.

1. Cutting-Edge Transducer Technology: Sound Motion

The standout feature of Arc Ultra is its revolutionary Sound Motion transducer technology, which is making its debut in this device. This technology drastically reduces the size of the transducers (the components that convert electrical signals into sound) while delivering bigger and more immersive sound from smaller components. This innovation allows for deep, room-filling bass and crisp, clear audio in a more compact package than traditional soundbars.

Whether watching an action-packed movie or listening to a quiet dialogue, the 14 Sonos-engineered drivers (including the Sound Motion woofer) work harmoniously to produce a 9.1.4 Dolby Atmos spatial audio experience. This means the sound moves around the room in a three-dimensional space, enveloping you in content and making you feel like you're part of the action.

2. Unmatched Vocal Clarity

Sonos has paid special attention to vocal clarity with Arc Ultra. The soundbar features a new center channel architecture that maximizes dialogue clarity, ensuring you never miss a word or whisper. Additionally, Arc Ultra introduces an advanced Speech Enhancement feature, allowing you to adjust dialogue clarity levels directly through the Sonos app to match your listening preferences.

3. Collaborations with Movie Producers for Cinematic Sound

The cinematic experience that Arc Ultra delivers is no accident. Sonos has collaborated with industry veterans like Chris Jenkins and Onnalee Blank, who have fine-tuned the device to optimize Dolby Atmos content playback. The result is a studio-quality sound system that rivals professional setups, bringing a theater-worthy experience into your living room.

4. Sleek, Elegant Design

Arc Ultra is not just about sound—it's also about style. The soundbar is thoughtfully designed with a distinctive curved profile and a matte finish. Its slimmer appearance makes it easy to integrate into any home setup, whether mounted on a wall or placed on a credenza. The design ensures it doesn't obstruct TV bezels, providing a clean and modern aesthetic.

5. Easy Setup and Control

Setting up Arc Ultra is simple and user-friendly. With just an HDMI eARC connection, you can unlock theater-quality sound in minutes. Control is equally effortless, with options to use your TV remote, the Sonos app, Sonos Voice Control, or Amazon Alexa. Arc Ultra also comes with Bluetooth line-in, allowing you to stream your favorite content.

6. Sustainability Commitment

Sonos is committed to sustainability, and Arc Ultra reflects this ethos. The soundbar is designed with improved serviceability, using more screws and fewer adhesives. It also reduces idle power consumption by up to 20% compared to its predecessor, Arc. Furthermore, the packaging for Arc Ultra is 18% smaller and 100% recyclable, making it more efficient to ship and environmentally friendly.

Sonos continues to raise the bar in home theater sound with the release of the Sonos Sub 4, the next-generation subwoofer designed to complement the Arc Ultra soundbar and provide a truly immersive audio experience.

1. Powerful, Pulse-Pounding Sound

The Sonos Sub 4 is engineered to deliver deep, dynamic bass that you can feel in your chest. Its dual custom woofers produce low frequencies that enhance the sound of movies, shows, and music, making every explosion, roar, or beat more intense. Moreover, the woofers face inward to create a force-canceling effect, eliminating distortion and ensuring a clean, immersive bass experience without unwanted buzz or rattle.

2. Upgraded Internals for Better Performance

Sub 4 is Sonos' most advanced subwoofer, featuring increased processing power and memory for superior performance. Additionally, including new WiFi radios ensures better connectivity and seamless integration with your home theater system.

3. Iconic Design, Refreshed

Sonos has maintained the iconic sculptural design of its previous subwoofers with Sub 4 but has updated it with a matte finish in both Black and White to match your Sonos system. Its flexible design allows it to stand upright, lie on its side, or be tucked under furniture, giving you versatile placement options. Additionally, the subwoofer has been made more sustainable with a redesigned enclosure and cable cover.

4. Elevate Your Home Theater

When paired with Arc Ultra, Arc, or Beam, Sub 4 adds new depth and dimension to your content, creating a breathtaking home theater experience. (Note: Arc Ultra can also be paired with Sonos Ace headphones.). For those looking for maximum bass, you can pair two Sub 4 subwoofers to take your audio experience to the next level. Importantly, Sub 4 is also compatible with previous generations of Sonos subwoofers, allowing for flexible upgrade paths for existing users.
