Customers are saying

Customers recognize the Sub 4 Wireless Subwoofer for its excellent sound quality and impactful bass. Users appreciate its sleek design and the convenience of its wireless connectivity, making setup quick and easy through the Sonos app. However, some customers have noted the high price point and potential compatibility issues with older Sonos devices. Despite these drawbacks, the subwoofer's power and relatively compact size are also appreciated.

    Sonos Sub Gen. 4

    The Sonos Sub Gen 4 is a fantastic addition to any home theater setup. From the moment I added it, the bass became deeper and more powerful, making movies and music feel much more immersive. Explosions and action scenes hit harder, and the sound feels like it surrounds you, bringing the whole experience to life. When paired with the Sonos Era 300s and the Sonos Arc Ultra, the sound quality is incredible. The Era 300s handle the mid and high tones with great detail, the Arc Ultra adds rich surround sound, and the Sub Gen 4 fills in the low end with booming bass you can feel. Together, they create a full, lively soundstage that makes watching movies way more exciting. The main downside is the price but it’s definitely a premium setup. But for the quality and seamless integration Sonos offers, it’s worth it if you want top-tier sound. The wireless design and build quality make it easy to use and stylish too. If you want your sound to feel alive and immersive, this combo is a killer choice.

    Look great and sounds great. Can't tell the difference from a gen 3. The mate finish goes with the rest of the sonos line. I have two arcs in the living room one already has a gen 3 sub. This will go on the other arc or it could be a second sub on the first arc. Also have two fives in the living room. All of them playing music at once sound pretty amazing. You can notice a difference with a second sub. You could just turn up the bass on one sub. It does sound even better with two also evens out where the bass is coming from. Seems to be coming from everywhere. Also says made in China. My gen 3 was made in Malaysia.

    This Sonos subwoofer is emasculate. The sound is just like the theater. It’s pairs very well with the Sonos arc ultra. It works great with music as well as thriller, horror, and action movies. I definitely give this 10 stars if I had to. This was one of my greatest purchases and I will be buying more Sonos products.Lets just say everyone wants to come over and enjoy the sound. Pop some popcorn, sit back and enjoy the theatrics!Very easy setup on your phone and it took about 5 minutes.

    I purchased this subwoofer with the Sonos Arc Ultra soundbar. It was easy to integrate with my tv to replace an existing LG soundbar and system. The sound was at least 10 times better. It is also aesthetically attractive and even my wife did not complain.

    Running an Arc soundbar, two Gen 3 subs, two Ones on stands, and a Holly smokes. I don't recommend this if you're in an apartment; it will annoy your neighbors. I also installed Sonance ceiling speakers and outdoor Mag 6 powered by Sonos. The speakers are Sonance. I added a pair of Ones and a Gen 4 sub in the kitchen, a One in the dining room, and four in-ceiling speakers in the loft, powered by a Sonos amp. Sure, the price adds up, but the point is, you start small and grow as needed. The amazing part is this product is all running off my Wi-Fi. Added tip: you will need good Wi-Fi and Wi-Fi products if you don't want interruptions. Overall, 10 out of 10, and that's me being honest!

    Sonos is a great line of audio equipment. I have a Sonos arc ultra, two era 300s and I added two sub 4 woofers. I am proud to say I now have a movie theater in my house. One sub 4 is great but two is even more wonderful I highly recommend.

    Originally just bought the ARC ultra, and it was fine without the sub... But then... Curiosity got the best of me. Honestly the sub is very much worth it. Get the Sub 100%

    This sub is one of 4 Sonos products I have. The bass is clear and shakes the room at low volumes. I usually have my sub set at -3. And it goes to +15.
