Sonos Sub 4 Premium Wireless WiFi Subwoofer – White (SUBG4EU1)

Description

Complete your Sonos home theatre with the Sonos Sub 4 Premium Wireless WiFi Subwoofer – White (SUBG4EU1). Designed to pair seamlessly with compatible Sonos soundbars and speakers, the Sub 4 delivers deep, powerful bass that brings every movie, TV show, game and playlist to life with remarkable clarity and impact.

The dual Sonos-engineered 5 × 8-inch elliptical woofers are positioned in a force-cancelling configuration to virtually eliminate cabinet vibration and distortion. A ported acoustic enclosure, dual Class-D digital amplifiers, and updated internal electronics—including a quad-core processor and WiFi 6—ensure exceptional low-frequency performance, improved responsiveness, and future-ready connectivity. The Sub 4 extends bass response down to 25Hz, allowing paired speakers to focus on crisp mids and detailed highs for a richer overall soundstage.

With Trueplay™ room tuning (supported iOS device required), simple setup through the Sonos app, and the flexibility to stand vertically or lie horizontally, the Sub 4 blends beautifully into any modern living space thanks to its elegant matte white finish.
