Sub 4 unlocks the full power of Sonos sound, delivering powerful bass to immerse you even deeper in every scene and song.
Pulse-pounding bass
Dual Sonos-engineered drivers generate deep, dynamic low frequencies. The ported enclosure enhances the bass response so you feel every beat, roar, and rumble in your chest.
Transform your home theatre experience
Pair Sub 4 with Sonos Arc, or Beam for dramatically deeper bass and clearer highs that draw you deeper into movies, shows, and games.
Bring your music to life
Hear the nuance in every note and enjoy a greater sense of spaciousness when you pair Sub 4 with Sonos Five, Era 300, or Era 100.
Iconic design
With its elegant sculptural shape and updated matte finish, Sub 4 is designed to look great in your home and to match your Sonos speakers.
Place it where and how you want
Sub 4 reliably connects to your Sonos soundbar or speaker over WiFi so you can place it anywhere in the room - even on its side and under your sofa. It is designed to provide optimal sound wherever you place it.
