Sonos Sub 4 Premium Wireless Subwoofer

I’ve been using the Sonos products ever since they started in business many years ago. The value proposition is simple and you put it anywhere you want and you don’t need to worry about the wires or a power supply. There’s a huge advantage to powered speakers that are workable, which is why they’re one of the best selling brands on the market. I owned and I do own lots of the Sonos sub GEN three’s and they’ve always worked beautifully and I was going to add another one and when they came out with the GEN four it was a no-brainer.

The connectivity on this was slightly faster and the look in the mat is much nicer. Not much more to say other than it worked beautifully and sounds great.

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.

I consider myself an audiophile and have a well-equipped home theater setup with an AV receiver and Dolby Atmos 5.1.4 sound. However, I also have a TV mounted in my great room where I have a pool table. To enhance the sound quality in that area, I connected a Sonos Beam to the TV, but I noticed that the soundbar alone lacked sufficient bass. Therefore, I decided to purchase the Sonos Sub 4, Sonos’s top-of-the-line subwoofer, to assess its impact on my overall sound quality and compare it to my home theater SVS PB2000 Pro.

The setup process was challenging. I recently installed a new Wi-Fi mesh system, and after numerous attempts to connect the sub to the app, I discovered that most Sonos products require a solid 2.4 GHz signal. Mesh systems can cause issues because your phone needs to be on the same frequency as the speakers. I suspect that my phone kept switching between 2.4 and 5 GHz because whenever I added the Sub, the app would display no connection. However, after accessing my router settings and splitting the signals, I was able to successfully set up the Sonos sub.

The Sonos Sub 4 offers limited features. You can adjust the volume of the bass, but that’s about it. The sound quality of the sub is clear and can produce a deep, rumbling bass during certain movie scenes. I tested some intense bass scenes, and the sub never failed to deliver, but it also didn’t quite reach the same low, rumbling depths as my home theater sub. Testing the sub with music was a more enjoyable experience. The bass was crystal clear and punchy, especially when listening to heavy bass songs.

If you choose to purchase Sonos, you’re limited to two subwoofer options: the Sub 4 and the Sub mini. At the time of writing this review, the Sub 4 costs $800, which is quite expensive. Considering that there are many other soundbar combinations with subwoofers that offer comparable features at a more affordable price, the Sonos Sub 4 may not be the most cost-effective choice. However, if you’re a fan of Sonos and appreciate its versatility in home audio, the Sub 4 is a must-have for a home theater setup.

This wireless subwoofer may not offer the same level of sound quality as a 10” ported sub connected to an AV receiver, but it provides a decent tradeoff for its wireless convenience and ability to easily connect to multiple Sonos speaker systems. If you’re considering a Sonos soundbar for your home theater setup, this subwoofer is definitely worth considering.

I can barely hear any base from this speaker, even with volume at 100%.

Do not buy, sony couldn’t pay me to use this speaker.

Amazingly small for the sound it puts out. I swear it sounds as good as the 12″ sub on my old home theater system.

I had night 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!

I finally decided to upgrader from my LG sound system. I wanted something to utilize Dolby Atmos and be a bit more immersive. I finally decided to go with the Sonos system. I bought the new Arc Ultra soundbar and 2 era 300s, and the Sub 4.

I have to say I’m very impressed with the entire system. Now for the sub specifically.
First off… The sub is beautiful. I got it in black and it simply fits into the decor and it’s barely noticeable! When you do notice it it doesn’t really look like a subwoofer. You honestly could mistake this for a piece of art.

The sub paired up easily to the system and it sounds phenomenal. I initially used the true tune for the entire system, but realized I wanted a little more control over the system specifically the bass so I manually tuned it and that’s when I really heard what the subwoofer was capable of.

The bass is very deep and punchy. If you’re not careful, it can definitely overpower your room. the controls within the app make it easy to adjust the subwoofer. You can adjust the phase and the volume of the subwoofer to get it to sound just how you want.

I’m shocked that this small sub can put out so much sound! I am extremely happy with t subwoofer as well as the entire system. I don’t hesitate to recommend this to anyone looking for a really good sound bar system!

Love, love, love. Fantastic subwoofer.

This is simply so absolutely cool. The sound is amazing, the build quality and visual is outstanding, and the setup was a breeze. This really adds a previously missing dimension to your listening experience if you are an existing Sonos user with a current subwoofer. Just transformative. A big investment, but the payback is even larger.

The Sonos Sub 4 has significantly enhanced my audio experience. Its elegant matte finish not only complements my home decor but also resists fingerprints, maintaining a clean appearance. I appreciate the flexibility in placement; while I prefer the traditional upright position, the option to lay it flat offers versatility for various layouts.

The bass performance is outstanding, deep, rich, and immersive, elevating both music and movie experiences. Compared to my other Yamaha 9.1 theater system subwoofer, the Sub 4 delivers a more powerful and refined low-frequency response. Notably, it eliminates the buzzing noises I previously encountered, resulting in a cleaner and more enjoyable listening experience.

Currently paired with the Sonos Beam, the Sub 4 has already exceeded my expectation. It has tempted me to consider upgrading to the Arc Ultra for my living room setup, oh no.

Overall, the Sonos Sub 4 combines aesthetic appeal with superior sound quality. Now the argument is just coming down to the price.
