Sonos Sub 4

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.
