Sonos unveiled three powerful new additions to its lineup — the Arc Ultra soundbar, Sub 4 subwoofer, and Era 100 Pro speaker — marking a bold leap forward in immersive home and professional audio.

Headlining the launch is Sonos Arc Ultra, a premium soundbar debuting the brand’s breakthrough Sound Motion™ technology – an innovation that drastically reduces the size of the transducer while supercharging bass output. Arc Ultra delivers up to double the bass of its best-selling predecessor, offering an unprecedented 9.1.4 spatial audio experience in a sleek, sophisticated design. Adding to the home theatre experience, Sub 4 builds on the iconic subwoofer’s legacy with deeper, more dynamic low end and a refreshed aesthetic.
The Era 100 Pro marks Sonos’ hardware debut with its first product designed specifically for professional installation in light-commercial and residential spaces. With a sleek design and premium sound, Era 100 Pro brings simplified setup through Power over Ethernet+ (PoE+), flexible installation with pro-grade mounts, and greater customization with Zones, a new software tool for managing larger-scale installs.
“We are excited to bring Sonos Arc Ultra and Sonos Era 100 Pro to India, meeting the growing demand for premium, immersive sound in both homes and commercial spaces. Arc Ultra is a groundbreaking evolution of our best-selling soundbar and as Indian audiences shift from the big screen to the home screen, Sonos brings the magic of the movies home with unprecedented sound in a sleeker design”, said Rennie Addabbo, General Manager Sonos APAC. “Whilst India’s new wave of experiential retail spaces, and desire for luxury stays and new residences cater perfectly for installers seeking to provide easy-to-use and exceptional audio solutions to their end-customers with Era 100 Pro.”
Arc Ultra & Sub 4: Breakthrough Sound for Your Home Theatre
Built with first-of-its-kind technology and deep industry collaborations, Arc Ultra provides boosted bass, a spine-tingling spatial audio experience with Dolby Atmos®, and advanced Speech Enhancement— all in a sleek package that blends into your space and complements large TVs. Whilst Sub 4 adds pulse-pounding sound and a refreshed design to elevate the home theatre experience.
- Theater Sound in Your Living Room: Arc Ultra delivers a massive sound stage that precisely places every detail of sound in your room to envelop you in content. The all-new architecture features 14 Sonos-engineered drivers, including a Sound Motion™ woofer and a cluster of tweeters with waveguides on both ends to deliver a 9.1.4 spatial audio experience. Tune with Trueplay™ to pinpoint the best sound for your space, now available for both iOS and Android.
- Never Miss a Word or Whisper: With a new center channel architecture, Arc Ultra maximizes vocal clarity so it’s easier to follow dialogue. An all-new advanced Speech Enhancement feature lets you choose your preferred level of dialogue clarity in the Sonos app.
- Cinematic Collaborations: Arc Ultra is the product of deepened Sonos Soundboard relationships. We worked with veteran movie producers and creators like Chris Jenkins and Onnalee Blank to fine-tune Arc Ultra for Dolby Atmos content playback and assemble a studio-worthy experience that rivals professional sound systems.
- Design Worthy of Your Home: Arc Ultra is thoughtfully crafted with a distinctive curved profile, matte finish, and a slimmer appearance.
- Seamless Setup and Control: Unlock theatre-quality sound in a matter of minutes with a simple HDMI eARC connection and effortlessly control with your TV remote, the Sonos app, Sonos Voice Control, or Amazon Alexa. Touch controls are cleverly housed in a dedicated ledge behind the soundbar to prevent visual distraction. With Bluetooth line-in, Arc Ultra also gives you more ways to stream – whether binging a podcast or setting a playlist before guests arrive.
- Committed to Sustainability: Arc Ultra was designed responsibly with improved serviceability by using more screws and fewer adhesives, halogen-free PCB materials, less silicon material, and a reduced idle power consumption by as much as 20% as a standalone player compared to Arc. Its packaging is 100% recyclable and also 18% smaller in volume, making it more efficient to ship. Whilst Sub 4 comes with a 50% reduction in idle power consumption.
- Pulse-Pounding Sound: Sub 4’s dual custom woofers generate deep, dynamic low frequencies to enhance your entertainment. No buzz or rattle either — both Sub 4 woofers face inward to create a force-canceling effect that neutralizes distortion.
- Rebuilt, Inside and Out: Sub 4 includes increased processing power and memory, as well as new WiFi radios for better connectivity so you never miss a beat. Maintaining much of its predecessor’s aesthetic, it showcases an updated matte finish in Black and White.
Built for Professional Installation
With the rich sound, elegant design, and versatile control that Sonos is known for, Era 100 Pro has been specifically designed to provide a complete, end to end solution for professional installation.
- Power over Ethernet: Simplifies installation by delivering both power and data through a single cable, removing the need for AC mains. Optimized for PoE+ as well as standard PoE, Era 100 Pro offers enhanced reliability, high-speed performance and easy integration into existing networks through wired-first networking.
- Customizable with zones: Zones makes it easier to orchestrate and control larger scale install by grouping speakers into a unified system that stays consistent throughout use.
- Versatile Surface Mount & Safety enhancements: Sonos Era 100 Pro integrates seamlessly into commercial or residential settings with pro-grade mounts (sold separately in pairs) that offer 360-degree rotation and 30-degree pan and tilt. Its indexed ball joint design allows for precise positioning, while a secondary safety attachment ensures compliance with building codes for secure installation.
- Premium sound: Leveraging the same acoustic architecture as Era 100, Era 100 Pro provides high quality sound and impressive low frequency performance, unique within the PoE speaker category.
