Our take on the Sonos Sub (Gen 3)

The Sonos Sub (Gen 3) is a wireless subwoofer with two force-canceling 6-inch drivers mounted face to face, driven by 245 watts of amplification and reaching down to about 25 Hz. The force-canceling design keeps cabinet vibration low, so it can sit upright almost anywhere in a room without rattling nearby objects. It pairs over Wi-Fi with Sonos soundbars and speakers for 5.1 home cinema and multi-room audio, and it works with Alexa and Google Assistant. Against cheaper third-party subs it costs more and only fits the Sonos ecosystem, but owners say it adds depth and punch that soundbars alone cannot match.

Questions and answers

Does the Sub Gen 3 work with any soundbar?
No. It pairs only with Sonos speakers and soundbars, such as the Arc, Beam and Ray, through the Sonos app.
Can I use two Subs together?
Yes. Compatible Sonos systems can run two Subs for more even bass, though most rooms do not need it.
Where should I place it?
It can stand upright or lie flat, and the force-canceling design lets it sit close to walls or furniture without rattling.
Does it need a wired connection?
No. It connects wirelessly over Wi-Fi, though it has an Ethernet port if you prefer a wired network link.
Is it worth it over a cheaper subwoofer?
If you already own Sonos gear, its clean bass and simple wireless setup justify it. If not, a third-party sub costs less but will not integrate.
Can I use it outdoors?
No. It is not weatherproof and is meant for indoor use only.

At Wichita Furniture & Mattress, for $599.00, 23% under what the other stores charge, as of our latest check.
