Deep and Dynamic Bass
Dual Force-Canceling Elliptical Woofers
The two inward-facing 5" x 8" elliptical woofers generate deep, dynamic bass. The force-canceling design creates an effect that virtually eliminates distortion, allowing you to feel every beat, roar, and rumble in your chest without buzz or rattle.
Ultra-Low Frequency Response
With a frequency response as low as 25Hz, the Sub 4 reproduces the deepest bass, from movie explosions to electronic music basslines, with exceptional clarity and power.
Two Class-D Digital Amplifiers
The two Class-D digital amplifiers are perfectly tuned to the subwoofer's unique acoustic architecture, providing precise power and control across the entire bass range.
Ported Cabinet
The ported cabinet enhances bass response and low-frequency output, allowing the Sub 4 to reproduce deep bass even in smaller spaces.
Transformed Home Theater Experience
Compatible with Premium Soundbars
Pair the Sub 4 with the Sonos Arc Ultra, Arc, or Beam Gen 2 for dramatically richer bass, clearer highs, and deeper immersion throughout your entertainment.
Full Surround Sound
The Sub 4 handles the lowest frequencies so your paired soundbar can deliver highs and mid-frequencies with even greater clarity and precision, creating a balanced and powerful sound system.
Dual Subwoofer for Maximum Drama
Pair two Sub 4 subwoofers with the Arc Ultra for bass so deep and sound so immersive you will forget you are at home and not in a real theater.
High-Fidelity Music
Compatible with Premium Speakers
Bring music to life with greater detail and enjoy a more spacious soundstage when you pair the Sub 4 with the Sonos Five, Era 300, or Era 100.
