Best For
The Sonos Sub Gen 3 and Sonos Sub 4 are premium wireless subwoofers designed to enhance the performance of compatible Sonos soundbars and speakers. Both models deliver deep bass down to 25Hz, feature force-cancelling driver designs to reduce distortion, and share the same iconic cabinet dimensions. The key difference lies in the internal hardware. While the Sub Gen 3 offers higher rated RMS output, the newer Sub 4 introduces upgraded electronics, a faster processor, increased memory, and Wi-Fi 6 connectivity. If you're building a modern Sonos home theater setup, choosing between proven performance and newer technology is the main consideration.
Verdict
The Sonos Sub 4 is the better choice for most buyers thanks to its updated hardware platform, Wi-Fi 6 support, improved processing power, and better future compatibility within the Sonos ecosystem. However, the Sonos Sub Gen 3 remains an excellent option for users who prioritize raw power output and can find it at a lower price. For new Sonos installations, Sub 4 is the safer long-term investment.
