Next Gen Ready

Featuring updated internal electronics, including a faster processor, more memory, and a new Wi-Fi 6 Radio—the Sub 4 is our most sophisticated Sub yet.

Sustainable Power

Showcasing a greener product design, Sub Gen 4 reduces idle power consumption by up to 50%.

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.

Place it where you want

Sub 4 connects to your system over Wi-Fi, so you can place it where it fits and looks best in the room.
