Pulse-pounding power
Dual Sonos-engineered drivers generate deep, dynamic low end. The ported enclosure enhances the bass response and low-frequency output so you feel every beat, roar, and rumble in your chest.
Transform your home theatre 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-cancelling 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™ optimises 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 lying flat and put it under your sofa.
Iconic design
Made to be seen, heard and felt. Sub 4 features an elegant sculptural shape and updated matte finish that perfectly matches your paired Sonos soundbar or speaker.
Plug and play
Simply plug in the power cable and open the Sonos app to quickly add Sub 4 to your system.
Place it where you want
Sub 4 connects to your system over WiFi, so you can place it where it fits and looks best in the room.
