    The Sonos Sub Gen 4 is an excellent addition to any Sonos home audio setup, offering deep, distortion-free bass that significantly enhances movies, music, and TV audio. Its design features dual opposing drivers that cancel vibrations and deliver precise low-end frequencies down to 25 Hz.

    Incredible, genuinely for the size of the thing the bass it produces is spectacular. Paired with a beam gen 2, it's like having a mini home theatre.

    It may not be the best sub on the market but seems well paired with Arc Ultra. Some music sounds better with Arc alone. I did try the Sub Mini as well to see if Sub 4 was overkill. But the Sub 4 won out easily. Occasionally just feel setup is boomy, but not on everything. Pleased overall

    Amazing what this little sub does to a Sonos system. Takes all the low frequency off of the surrounds and soundbar and makes the sound so much more accurate and full.

    I have an Arc, and two Era 100 as surrounds along with my LG 55 in my home office. Although the arc is impressive, I felt the lack of bass below 100hz. So, I read up on whether to pair the Arc with the Gen 3 sub or the sub mini. Online audiophiles recommended that you answer two questions: 1) Size of room and 2) do you want to rattle your neighbors and feel it in your chest. Since my room wasnt large (eg <300’ sq) and i didnt want to disturb my neghbors (or wife) i chose the sub mini. I’m very happy with my choice. After running Truplay set up, the sub adds in the bottom end nicely, filling in the whole in the Arc, to a well balanced signal down to 25hz for movie soundtracks as well as classical symphony. Nice flatline from 25hz on up. Now, that said, i did experiment further and found the sub mini to also be very impressive when i wanted to watch an action film like “Extraction” with cinema quality, heart throbbing bass (& my wife’s out of the house and my neighbors are gone)… I simply go into the Sonos settings and turn up the sub volume +5 to + 7 (out of +15) and you get all the oomph of chest pounding bass you’d expect from a sub. Im thrilled - particularly for not shelling out the extra $400 for the gen3 full sub. Clearly not needed in my scenario. YMMV.

    This is a great subwoofer. I love that you can place it just about anywhere - even slide it on its side under a couch if you have to. Deep and well-controlled bass - Integrates so well with my Sonos speakers. A little pricey, but worth it.

    This thing is slim and sleek. The size in relation to the output is crazy! Scalability is performed with ease via the Sonos App. Get the bigger option even for small spaces. Spend the extra money - you’ll be glad you did.
