Product Details

Description

The Sonos Sub 4 is a premium wireless subwoofer designed to add deep, controlled bass to compatible Sonos soundbars and speakers. It works beautifully with Sonos Arc Ultra, Arc, Beam, Era 300, Era 100, and Five, making movies, music, games, and TV sound fuller, more powerful, and more immersive.

Its dual 5 x 8-inch elliptical woofers face inward to create a force-canceling design that helps reduce vibration, buzz, and distortion. The ported enclosure extends bass response down to 25 Hz, giving soundtracks more weight, music more body, and action scenes a stronger sense of impact without muddying the rest of the sound.

Sub 4 connects wirelessly over Wi-Fi and can be placed upright or laid flat, giving more flexibility in living rooms, media rooms, and home cinema setups. With Trueplay tuning, app-based EQ control, updated internal processing, and a clean matte finish, the Sonos Sub 4 is built for listeners who want powerful low-frequency performance with simple setup and elegant room integration.
