Sonos Sub 4 | Wireless Subwoofer with Powerful Bass for Immersive Entertainment – Black

Sonos Sub 4 – Wireless Subwoofer That Brings the Cinema to Your Living Room

The Sonos Sub 4 is the fourth generation of Sonos’s acclaimed wireless subwoofer, and it represents the most refined, most powerful, and most intelligently engineered bass experience that Sonos has ever delivered. Designed to pair seamlessly with Sonos soundbars and speakers, the Sub 4 adds a dimension of low-frequency depth and physical impact that transforms the way you experience music, movies, TV shows, and games. When you feel the rumble of an explosion, the thunder of a kick drum, or the deep resonance of a double bass, you understand why a dedicated subwoofer is not a luxury – it is a necessity for truly immersive audio.

Fourth Generation – Refined in Every Way

Sonos has spent years perfecting the Sub. Each generation has brought meaningful improvements in acoustic performance, wireless connectivity, and integration with the Sonos ecosystem. The Sub 4 continues this tradition with a redesigned driver configuration, enhanced amplification, and Sonos’s latest wireless technology. The result is a subwoofer that goes deeper, plays louder, and integrates more seamlessly than any previous Sonos Sub – while maintaining the iconic, award-winning industrial design that has made it one of the most recognisable audio products in the world.

Dual Force-Cancelling Woofers – Deep Bass Without Vibration

The engineering centrepiece of the Sonos Sub 4 is its dual force-cancelling woofer configuration. Two custom-designed woofers are mounted facing each other inside the Sub’s sealed cabinet, operating in perfect opposition. As one cone moves forward, the other moves backward simultaneously, so the mechanical forces generated by each driver cancel out rather than adding together. This force-cancellation eliminates the cabinet vibration and rattle that affect conventional subwoofers with a single driver, allowing the Sub 4 to operate at high volumes without transmitting unwanted vibration to your furniture, floor, or walls. The result is bass that is extraordinarily clean and controlled – powerful when the content demands it, composed and precise at all times.

Class-D Amplification for Effortless Power

Inside the Sub 4’s elegantly minimal enclosure are high-efficiency Class-D amplifiers, one dedicated to each woofer. Class-D amplification provides the headroom needed to reproduce the most demanding low-frequency transients – the sudden, deep bass impacts in action film soundtracks, the chest-thumping drops in electronic music, the foundational low end of orchestral recordings – without clipping, compression, or distortion. The amplifiers are matched precisely to the acoustic characteristics of the woofers, ensuring that every watt of power is converted into the deepest, cleanest bass possible.

True Wireless Integration – Zero Cables Between Sub and Soundbar

The Sonos Sub 4 connects to your Sonos soundbar – Arc, Arc Ultra, Beam, or Ray – entirely wirelessly using Sonos’s proprietary SonosNet mesh protocol. There are no audio cables to run between the soundbar and the subwoofer, giving you complete freedom in subwoofer placement. Position the Sub 4 wherever it sounds best in your room – next to the TV cabinet, to the side of the sofa, or behind a piece of furniture – without worrying about cable routing. The wireless connection is stable, low-latency, and perfectly synchronised with the soundbar’s output at all times.

Trueplay Tuning – Acoustically Perfect in Any Room

Every room is acoustically unique. The size, shape, furnishings, and surfaces of your listening space all affect how bass behaves – where it builds up, where it is absorbed, and how it interacts with the rest of the audio. Sonos Trueplay technology analyses your specific room using the microphone in your iPhone and automatically adjusts the Sub 4’s equalisation and output to deliver optimal bass performance in your actual space. This is not a generic preset – it is a personalised acoustic calibration that makes the Sub 4 sound exactly right in your room, with your furniture, on your floor.

Iconic Design That Complements Any Interior

The Sonos Sub 4 is as beautiful as it is powerful. Its distinctive oval form with a through-hole centre slot is unmistakably Sonos – a piece of industrial design that has won international awards and graced the pages of design magazines as well as audio publications. The gloss black finish (also available in white) is crafted from high-quality materials and resists fingerprints and dust. The Sub 4 is a speaker that enhances the aesthetic of any room rather than hiding in a corner. Whether it stands vertically beside your TV cabinet or lies horizontally beneath a media unit, it looks purposeful, refined, and premium.

Simple Setup with the Sonos App

Adding the Sub 4 to your Sonos system takes less than two minutes. Open the Sonos app, select Add Product, and follow the on-screen instructions. The Sub 4 pairs automatically with your soundbar and is immediately optimised for your system configuration. From that point on, the Sonos app gives you complete control over the Sub’s level, allowing you to adjust how much bass is added to suit your content, your mood, and your room’s acoustics – all from your smartphone, without touching the Sub itself.
