We have the ultra arc soundbar the sub 4 wireless subwoofer is the perfect match Easy to set up and make listening to movies and music so much more a Enjoyable

Upgraded my Sub 3 to a Sub 4. I definitely feel that there is more bass, subtle, but a deeper bass. As usual, a sleek, modern design, it looks and feels premium. It’s also quite a bit lighter than the 3, which is nice! Sonos bass is deeper and more “punchy” than the previous Samsung surround I had and a definite upgrade. Extremely easy to set up the Sub 4. I may not have figured it out yet, but I do wish there was a “sound field” to set up where one would be for music and the other for movies. My movie bass is always deeper than the music bass and I find myself having to put the bass higher when switching back to movies.

Excellent sounding speaker in setup with arc ultra and era 300s. I bought stands for the era 300s from Amazon that keep them at the perfect height. Run software that sets the sound levels for all the speakers and you will not be disappointed. The sub adds that extra oomph to the sound, however depending on the situation may not be needed because soundbar does have good bass

Amazing sound, powerful addition to the system, perfect size, easy integration

Easy setup, great sound, great product. Easy app integration and sync with my other sonos effortlessly.

Excellent product. Deep satisfying bass. Plus necessary adjustments available through the Sonos app on my phone. I was so happy with this sub 4 that I purchased the second one. Now my system resembles the movie theaters. Very happy

The price is a bit steep. I bit the bullet and got the sound bar and sub on Black Friday Deal. AllI can say is WOW. By far the best sub i have ever heard. It doesnt vibrate the whole house. No, its classier than that. It fills the room with a much more elightening form of bass. I’m amazed.

This product is wonderful, having a wireless subwoofer is just outstanding sounds great and it looks wonderful. I would definitely recommend it to anyone that have a Sonos set up..

The best addition to any home theater or home audio system- Sonos ecosystem remains superior and unparalleled to any other brand I’ve experimented with. This subwoofer will bring great audio range that you could only experience in a high end movie theater or car, with the power to shake my bed if I raised the subwoofer power a few notches, the range on this product is unparalleled.

Very positive online reviews. Was not disappointed, ease of setup, control & performance.

I use them, I have two, one in my small living room and one in the bedroom, but I decided to go with the GEN four versus the mini because as I found later with the Tuning app, let the system tune itself, then just simply bring up or down the base gain as needed. Easily done in the app. But I recommend don't adjust the equalizer base level as this will adjust the whole systems base response. Rather, just adjust the sub level or sub volume, down or up as needed. These are almost invisible units that can sit in the rear of the room or in front of the room, I guess they are non-directional, but have achieved great sound in their initial placement, so great for any installation purpose. Put these in anywhere and they will sound amazing.

Premium sound, premium product all around. Looks elegant and can’t say enough how much we love it! Worth the price.

This is an incredible sub! I also happen to have the Nakamichi Shockwafe. This Sonos has a similar room filling base, but it’s connectivity is where it really shines. Nakamichi uses wireless technology to connect, but it often cuts out. You also get stray base rumble. The Sonos is just perfectly connected clear, clean sound. The base is everything you could want from a single dub. It can also lay on its side, and it’s small enough to tuck under our bed. So it’s completely out of sight. This is overkill for a bedroom, but movies in bed with the Sonos surround, are next level awesome, if you’re a stepper!!

Amazing bass from such a compact and beautifully designed subwoofer. Vibrates a little with louder more intense bass, but I'm probably pushing it a little! 99% of the time, it is amazing

Excellent bass, though a bit expensive. I was able to find an open box - good item which worked perfectly, just had a little scuff on the side, which is very insignificant given the way I have it positioned. But the quality of the bass with the arc ultra and 2 100’s as surrounds is absolutely incredible. There are some adjustments you can make for the bass via the app, and I personally increased the bass output to +5 since I love that added bass for movies and shows I watch on the D+ app. And setting everything up via the app was seamless and a breeze.

Incredible bass sound in TV and movies that broadcast in stereo or surround. Easy connection and setup. Attractive design that looks good anywhere in room.

Sound is fantastic and the app makes adjusting a breeze

Excellent sound quality. The wireless connection is incredible and makes it easy hiding only 1 power cord.

Great sound and easy set up, makes listening to the big game or movie easy.

The Sonos Sub 4 is an absolute game changer. I already loved my setup, but adding the Sub 4 took everything to a completely different level. The setup was incredibly easy—just a few taps in the app and it was paired and ready to go. The bass is deep, clean, and powerful without being muddy or overwhelming. You don’t just hear it—you feel it. It adds so much depth to movies, music, and even regular TV. Action scenes hit harder, music sounds fuller, and the overall experience feels truly cinematic. If you already have a Sonos system, the Sub 4 is 100% worth the upgrade. It completes the sound in a way that makes you wonder how you ever watched anything without it.
