Sonos Sub 4 Black
Sonos's subwoofer: two elliptical woofers facing each other inside a body with a hole through the middle. Pushing against one another cancels the vibration, so it reaches down to 25 Hz without the furniture rattling.
Why people like it
- Down to 25 Hz — the bass a soundbar simply cannot produce at that size.
- No vibration — the two 5"×8" woofers face each other and cancel out the forces.
- Self-balancing — once paired, the system splits the frequencies between the Sub and the speakers.
- No audio cable — it only needs mains power and the Wi-Fi network.
