Subwoofer activo Sonos Sub 4 – amplificador clase D, AC 110–240 V, 40,2 × 15,8 × 38,9 cm, negro o blanco

Sonos Sub 4 is an active subwoofer with a Class D amplifier designed to extend low-frequency response for home audio systems. With AC 110–240 V support and compact dimensions (40.2 × 15.8 × 38.9 cm), Sub 4 adds deep, controlled bass while fitting near furniture and in living spaces. Dual force‑canceling woofers and a ported enclosure deliver strong low end with minimal distortion. The unit connects to a Sonos system over WiFi and is available in black or white; an AC power cable is included to simplify setup.

Advantages

Sub 4 produces powerful, pulse‑pounding bass through dual Sonos‑engineered drivers and a ported cabinet that increases low‑frequency output. The force‑canceling acoustic architecture reduces vibration and audible distortion, allowing clearer mid and high frequencies from paired speakers. Trueplay room tuning adapts bass response to the listening environment so lows remain balanced whether the subwoofer is freestanding, placed against a wall, or laid flat under furniture. The matte finish and sculptural shape integrate visually with Sonos soundbars and speakers while WiFi connectivity and simple app setup enable quick integration into existing systems.

Key specifications

How to use

Place Sub 4 where it fits best in the room — upright, on its side, or tucked under furniture. Plug the included AC cable into a mains outlet and power on the subwoofer. Open the Sonos app on a compatible device and follow the on‑screen instructions to add Sub 4 to an existing Sonos system or pair it with a Sonos soundbar or speaker. After connection, run the Trueplay tuning feature (if available on your device) to optimize bass response for the room. Use the Sonos app to adjust volume and group Sub 4 with other Sonos products for multiroom playback or home cinema configurations.

Recommendations

For best results, allow some space around the subwoofer to prevent muffling if placed in a very enclosed area. When pairing with a Sonos soundbar for home cinema, consider using one Sub 4 for balanced low end or two for maximum low‑frequency impact. Run Trueplay tuning after final placement to ensure bass is balanced with the room acoustics.
