Sub 4 unlocks the full power of Sonos sound to immerse you deeper in every scene and song.

Transform your home theater experience

Pair Sub 4 with Sonos Arc Ultra, Arc, or Beam for dramatically richer bass, clearer highs, and deeper immersion in all your entertainment.

Bring music to life

Discern every subtle detail and enjoy a more spacious soundstage when you pair Sub 4 with Sonos Five, Era 300, or Era 100.

No buzz or rattle

The acoustic architecture creates a force-canceling effect that virtually eliminates distortion.

Better sound all around

Sub 4 takes over the lowest frequencies so your paired soundbar or speakers can deliver high and mid frequencies with even greater clarity and precision.

Perfectly tuned for the room

Trueplay™ optimizes the sound for the unique acoustics of your space so the bass never sounds harsh, muddy, or flat — even if you place Sub 4 next to the wall or lay it flat and put it under your sofa.
