Sonos Sub 4 Wi-Fi Subwoofer, Black

The Sonos Sub 4 is a wireless subwoofer designed to add low-frequency extension to an existing Sonos sound system. It is equipped with two inward-facing bass drivers in a force-canceling configuration, a design intended to neutralize cabinet vibrations and minimize distortion. This architecture allows the subwoofer to handle frequencies down to 25 Hz, providing a dedicated bass channel for audio content such as movies and music. The unit functions exclusively as part of a larger Sonos setup, connecting wirelessly to other components.

The device connects to a home network via Wi-Fi for integration with Sonos speakers or soundbars. Its enclosure features a matte finish and can be positioned either vertically or horizontally to accommodate different room layouts, including placement under furniture. The subwoofer supports Trueplay tuning technology, which analyzes a room's acoustics to adjust the audio output accordingly for that specific space. Power is supplied to the unit through a standard AC connection.
