Adding the Sonos Sub (Gen 4) to my Arc Ultra soundbar was the best decision I’ve made for my home theater setup. While the Arc already delivers exceptional sound, the Sub takes it to an entirely new level by adding that deep, cinematic bass that you can feel as much as you hear. The sound is incredibly rich and immersive. Whether it’s an action-packed movie or a music playlist, the Sub provides those low-frequency tones that truly bring the experience to life. Explosions, rumbling effects, and bass-heavy tracks now feel like they’re happening right in my living room—it’s like having a professional movie theater at home. Setup was a breeze, just like with the Arc. The Sonos App made it simple to pair the Sub with my existing system, and fine-tuning the sound to fit my room was effortless. The wireless design also makes it easy to place the Sub anywhere in the room for optimal performance. I know some people debate whether the Sub is a "necessary" addition to the Arc, but for me, it absolutely is. If you want that room-shaking, heart-thumping bass that completes the home theater experience, the Sub is essential. I couldn’t be happier with this upgrade—it’s the perfect companion to the Arc Ultra soundbar and worth every penny for anyone who values premium sound quality. Highly recommend!

I had bought the Sonos Arc Ultra and was very impressed with it. For what it cost, I better be! I had no intention of getting the Sub 4, but I came across it on sale, and after doing a little reading about it, I did an impulse purchase. Like 5 minutes after seeing it on sale! Setup is simple, tweaked the level a bit higher, then brought up Saving Private Ryan and it was just at the beginning of the final battle scene where I had left of prior. I was stunned at how much the sub added to the whole experience! The rumbling of the tanks, explosions, gunfire, well, I literally felt I was sitting in the middle of the fight with the Sub 4 and the Arc Ultra. Sonos is not a cheap in price brand, but I am glad I splurged on all this to go along with a new Samsung TV. If you are in the fence about adding the sub--do it! You can actually add two Sub 4s to the Ultra. I've been thinking hard about it, but I think I would seriously annoy my next door neighbors, and my two pups get startled at times the way it is with the current setup :) Highly recommend--just get it!

Super simply put, the bass is truly a beast of a thing. Goodness gracious. It's worth the money if, like me, you a big lover of big bangin bass!!!

The bass is deep and clear. Sounds great with music or tv. The app lets you adjust to taste. It's a lot of money but it's the perfect companion to the arc ultra. I would buy again.

Tremendous bass with a sleek design and plug and play. Super simple!!! I really am enjoying it!

I had a Era 100 stereo pair and a sub mini in my Family Room and it sounds great. I have another Era 100 Stereo pair in my Living Room with a sub mini, but although good, the bass was lacking. So since you can't add another sub mini to a pre-existing stereo pair, I made a third Era 100 stereo pair w/ a sub mini and put the sub mini in the living room and had two subs going, giving me the sound I wanted. At the time I didn't want to spend $800 for a Gen 3 sub woofer and didn't like the piano black glossy finish. Two sub minis w/out tax is $858, so I didn't mind spending a little more for the two sub minis over the one Gen 3, granted i did have to purchase another Era 100 to make it work. Then there was the announcement of the Gen 4 coming out, with a matte finish. Prior to the Sub 4 being announced and released I had been asking myself, "What if? what if? So I got the Gen 4 thinking I could always return it. I set it up in my Living Room replacing one of the sub minis in the Era 100 stereo pair. I think I was expecting too much because I had read the Gen 3 was so powerful and some users even had to turn the bass down into the negative, so I really had high expectations for this sub woofer. I knew the output was the same as the Gen 3, just an updated processer and a matte finish. I played different tracks from Rap, pop, classical, country, dance mixes and although I noticed more bass from the Gen 4, I was like , "Meh". After True Play tuning it a few times , even advanced True Play I was a little disappointed. I tested the different music on the Gen 4 for about an hour and was left under-whelmed. I wasn't going to return this thing because 1. the box was too big, didn't want to go through the hassle and 2. it wasn't disappointing enough to warrant a return. Ultimately I ended up moving it to my Family Room and took the sub mini that was in my Family Room and put it in my Living Room. The two sub minis in my Living Room sound great, they were made for each other, compared to the Gen 4 and sub mini together. The Gen 4 sounds better in the Family room with the Era 100's and that is where I 'll leave it. All of my Sonos speakers are for music only as I already have a dedicated Home Theater. I've read the Gen 3, 4 are particularly better sounding with cinema because it's a ported speaker, whereas the sub mini is better for music because it's sealed. IDK, other than the shape the sub mini and Gen 4 are similar in respect because they both have facing sub woofers. One is boxy shaped the other is cylindrical in shape. All in all, my expectations were way too high, but in the long run I think I will enjoy the Gen 4.

Rich clean bass that pairs perfectly with my Sonos Arc Ultra

Sonos is so good, easy to setup and amazing performance

A pair of Sonos Bass 4s coupled with the Sonos ARC Ultra and a pair of ERA 300 produces a completely immersive and spatial audio for listening to music. Very impressive for music lovers!

Su estética, calidad y sonido

The best thing I have bought in a long time, great product

Excelente experiencia, lo puse al fondo de la sala y no se percibe que esté en esa zona de la sala, pareciera el efecto Subbufer proviene de la Sonos Arc q está bajo la TV

Sonos builds quality products you won’t be disappointed
