The Sub 4 unleashes the full power of Sonos sound, drawing you deeper into every scene and song.
By pairing your Sub 4 with a Sonos soundbar or speaker, you'll hear and feel the difference.
Two power-balancing woofers deliver pulsating bass and virtually eliminate distortion. The iconic design, updated with a matte finish, looks great in your home. Set it up in minutes—just plug in the power cord and open the Sonos app.
The Sub 4 connects to your system via WiFi, so you can place it wherever it looks good and fits best in the room. Place it upright or on its side and hide it under the sofa.
When you pair two subwoofers with an Arc Ultra or Arc speaker, you get such deep bass and cinematic sound that you'll forget you're not in a real theater.
Pulse-raising power
Dual Sonos-designed drivers create deep, dynamic low frequencies. A ported enclosure enhances bass response and low-frequency output, so you can feel every beat, roar, and rumble in your chest.
Transform your home theater experience
Pair the Sub 4 with a Sonos Arc Ultra, Arc, or Beam for dramatically richer bass, clearer highs, and deeper immersion in all your content.
Bring music to life
You'll notice every subtle detail and enjoy a more spacious soundstage when you pair the Sub 4 subwoofer with either the Sonos Five, Era 300 or Era 100 speaker.
No creaking or rattling
The acoustic architecture creates a force-balancing effect that virtually eliminates distortion.
Better sound everywhere
The Sub 4 takes over the lowest frequencies, so the paired soundbar or speakers can produce high and mid frequencies with even greater clarity and precision.
Perfectly tuned to the room space
Trueplay™ optimizes sound for the unique acoustics of your space, so the bass never sounds too loud, stuffy, or flat – even if you place the Sub 4 next to a wall, horizontally, or even under a sofa.
Iconic design
Made to look, sound and feel great, the Sub 4 speaker has a sleek, sculptural design with an updated matte finish that perfectly complements your paired Sonos soundbar or speaker.
Place it wherever you want.
The Sub 4 connects to the system via WiFi, so you can place it anywhere that is convenient and looks good.
