Know before you buy
Yes, the Sub 4 features a dual-orientation design, allowing you to stand it upright or lay it flat on its side to better fit your space.
No, the Sub 4 connects wirelessly to your existing Sonos system over your home Wi-Fi network. It also includes an Ethernet port if you prefer a hardwired connection.
Trueplay uses your mobile device's microphone to measure how sound reflects off the walls and furniture in your room. It then calibrates the subwoofer's output to ensure the bass is balanced and precise for your specific environment.
The Sub 4 is engineered with a force-canceling acoustic architecture. By positioning the dual drivers to face each other, the vibrations cancel each other out, resulting in deep bass without unwanted cabinet rattle or floor distortion.
The Sub 4 is designed to work with any amplified Sonos speaker or component, such as the Arc, Beam, or Era series. It is intended to be paired with a system that is already playing audio, as it does not function as a standalone speaker.
The Sub 4 is capable of producing low-end frequencies as deep as 25 Hz, providing the physical impact and rumble necessary for a cinematic home theater experience.
