Product Summary
The Sonos Sub 4 is built for customers who already like what their Sonos soundbar or speaker can do, but want more depth, more impact and a much bigger sense of scale. It is the sort of upgrade that can make films feel more cinematic, music feel fuller and everyday listening feel noticeably more substantial.
Rather than simply adding more bass for the sake of it, Sub 4 is designed to make the whole system sound more confident and more composed. By taking on the lowest frequencies itself, it allows your paired Sonos speaker or soundbar to focus more cleanly on mids and highs, which helps dialogue, detail and overall clarity come through better.
It is also very easy to place and live with. Because it connects over WiFi, you are not tied to awkward cable runs, and the dual-orientation design gives you more flexibility in where it can go. For customers wanting a cleaner, more powerful and more immersive upgrade for a compatible Sonos setup, the Sonos Sub 4 is an excellent choice.
