Our take on the Sub Gen 3

The Sonos Sub Gen 3 is a wireless subwoofer that adds deep bass to any Sonos speaker system, from a single One to a full Arc home theater setup. It uses two force-cancelling drivers facing inward, so it produces hard-hitting low end with very little cabinet rattle or vibration. Setup is cable-free through the Sonos app, and it pairs with almost every current Sonos speaker. Reviewers rate it highly for its clean, room-filling bass and its looks; the main complaints are its size, its weight and the fact that it only makes sense if you already own Sonos gear.

About the Sub Gen 3

Sub Gen 3 is a wireless subwoofer that adds to a Sonos system. It takes over the lowest frequencies, so the paired speakers can focus on the mids and highs. Two force-cancelling speakers are designed to remove vibrations and buzzing.

It connects to the system over Wi-Fi, and the Sonos app gives step-by-step setup instructions. The shape is sculptural with a glossy finish, and it can stand vertically or lie horizontally. Two Subs can be added to a Sonos home theater setup.

Questions and answers

Does the Sonos Sub Gen 3 work with any speaker?
It works with Sonos speakers only. It pairs with most current Sonos models, including the Arc, Beam, Ray, One and Era speakers, through the Sonos app.
Can I use two Subs together?
Yes. On supported Sonos home theater setups you can pair two Subs for more even bass across a larger room.
Do I need a cable to connect it?
No. The Sub connects wirelessly over your Wi-Fi network. It only needs a power outlet.
Is the Sub Gen 3 worth it over the Sub Mini?
The Gen 3 delivers more output and deeper bass, so it suits larger rooms and home theater. The Sub Mini is smaller and better for music in smaller spaces.
What is in the box?
The box contains the Sub Gen 3, a power cable and a quick start guide. No audio cables are needed.
Can I place it anywhere in the room?
Yes, placement is flexible, but bass response changes with position. The Sonos app lets you adjust the level, and trueplay tuning can help.
