Sonos SUB 4 WLAN Subwoofer

Sonos Sub 4

Wi-Fi subwoofer for powerful bass

The Sonos Sub 4 combines the latest technology with thoughtful design to deliver an outstanding audio experience. Two precision-engineered force-cancelling woofers produce bass frequencies without annoying distortion. With its housing, the subwoofer optimizes the reproduction of low frequencies and thus ensures a dynamic and thrilling sound that makes every detail audible.

Technical excellence for every home cinema
The Sub 4 reaches its full potential when combined with Sonos Arc Ultra, Arc or Beam. The result is a powerful bass that gives films and series additional depth, while the highs are reproduced more clearly and precisely. Music lovers also benefit when the Sub 4 is connected to Sonos Five, Era 300 or Era 100, as it feels like it expands the sound stage and makes even the finest nuances audible.

Optimized sound without compromise
Thanks to the innovative force-cancelling technology, the sound remains free of unwanted resonances. At the same time, the Sub 4 supports the speakers of the entire system by taking over the lowest frequencies and thus improving the clarity and precision of the mid and high tones.

Flexible placement and easy setup
The Sub 4 offers maximum flexibility: It can be positioned either vertically or flat, for example discreetly under a sofa. The connection is via WiFi, so there are no annoying cables to spoil the design. Setting it up is child's play - connect it to the power supply, open the Sonos app, and the Sub 4 is ready to use in just a few minutes.

Design that impresses
With its slim shape and matte finish, the Sub 4 blends seamlessly into almost any living environment. Whether as an eye-catcher or discreetly placed, the minimalist design harmonizes perfectly with the entire Sonos product range.

Trueplay™ technology for perfect adjustment
The Trueplay™ function calibrates the sound precisely to the acoustic conditions of the room. Even when placed close to the wall or under furniture, the sound remains powerful and unadulterated.

compatibility and expansion options
The Sub 4 is compatible with a wide range of Sonos products, including Arc Ultra, Arc, Beam (Gen. 1 & 2), Ray, Five, Era 300 and Era 100. For an even more immersive experience, two subwoofers can be connected to the Arc Ultra to create a soundscape that is in no way inferior to a cinema experience.
