Sonos’ new Arc Ultra soundbar & Sub 4 subwoofer turn your living room into a movie theatre

Sonos is levelling up your home theatre and commercial sound game with not one, but three major drops—Arc Ultra, Sub 4, and the new Era 100 Pro. While Arc Ultra and Sub 4 are built for that next-level cinematic experience in your living room, the Era 100 Pro is all about nailing the premium audio vibe in art galleries, showrooms, or office setups.

Arc Ultra and Sub 4 bring the boom with serious audio tech

The Arc Ultra is Sonos' flagship soundbar, and it's a beast. We're talking 15 Class-D digital amplifiers, seven angled silk-dome tweeters (two of them fire upwards for a full Dolby Atmos experience), and six midwoofers for clean dialogue and powerful mids. And then there’s the bass—it’s got a four-motor, dual-membrane Sound Motion™ woofer that literally hits you in the chest.

That’s not even the best part. Arc Ultra supports Trueplay tuning (now on both Android and iOS), which scans your room and adjusts the sound for the perfect vibe—whether you're in a tiny apartment or a huge open space. And if you're always struggling to catch what characters are saying, Arc Ultra’s new centre channel architecture and upgraded Speech Enhancement feature in the app ensure you don’t miss a whisper.

And Sonos isn’t doing this alone. They worked with Hollywood pros like Chris Jenkins and Onnalee Blank to fine-tune Arc Ultra for the ultimate Dolby Atmos playback. So yeah, it's basically like bringing a movie theatre home.

But if you want to take it even further, pair it with the all-new Sub 4. This wireless subwoofer packs dual 5x8” woofers in a force-cancelling setup with two Class-D amps, delivering gut-punching bass all the way down to 25Hz—minus the buzz or rattle. It’s like thunder in a box. Sub 4 also adds more memory, better WiFi radios, and comes in a slick matte black or white finish.

Arc Ultra and Sub 4 price in India: not cheap, but worth it

This level of high-fidelity audio doesn’t come cheap. The Arc Ultra is priced at ₹99,999, while the Sub 4 will set you back ₹84,999. But if you're chasing that wall-shaking, Dolby Atmos, feel-it-in-your-bones kind of sound—this duo absolutely delivers.

Era 100 Pro is all business—literally

While Arc Ultra and Sub 4 are for your home, the Era 100 Pro is built for professional spaces. Think showrooms, art galleries, boardrooms. The big win here? Power over Ethernet (PoE), meaning one cable handles both data and power—no wall sockets required.

It’s also remote-manageable via dashboard, perfect for running complex setups across different rooms. With the new "Zones" feature, you can easily group and control speakers by area.

The Era 100 Pro also mounts like a dream. With pro-grade, 360-degree adjustable brackets (sold separately), plus a secondary safety attachment to meet building codes, it’s made for seamless integration. Under the hood, it carries the same acoustic engine as the standard Era 100—so you get rich mids, crisp highs, and tight bass, all in a speaker optimised for commercial use.
