Great bass and so easy to setup. Done in less than 5 mins. Adds a whole new dimension to our surround sound system. Really complements our 2 ERA300's.

Great addition to sound system

Amazingly clear bass! Coupled it with my Arc Ultra and the sound is better than being in a theater. Never thought I'd need a sub, but very glad I got it. Easy to install also.

This Sonos Sub 4 completely transformed the bass production of my already installed Sonos in-ceiling speakers. It is a game changer and I am happy with the sound production.

Sonos Sub 4 is Fabulous and An Incredible Value

George from Summerfield, FL on 3/26/2025

Verified employee review (What's this?)

I was not expecting this level of bass from the Sonos Sub 4 in my main TV watching room!! To put this into perspective, I have a theater setup with two $2.6k each subwoofers. The Sub 4 impressed me at less than 15% the cost of my big subs!! Also I can customize the Sub 4 bass levels in the Sonos App and was very impressed with the level of control. Lastly, I have a couple of deep, deep bass tracks that I ran with the bass levels in the App elevated and there was nothing but clean deep bass. I highly recommend the Sonos Sub 4!!

Great product, awful App, equals poor system

Richard from Melbourne, FL on 2/18/2025

Verified employee review (What's this?)

Can you get the App and Device to work in harmony? The Sub 4 was up and running within 10 minutes of me receiving it? Amazing! If only this ease of connection had continued! No the Sonos App hits once again. I wanted to move the Sub and so I turned off the power and moved it; would it come on again no. I spent a very frustrating hour trying to follow the instructions in the App and all to no avail. I worked through my own solution by trial and error. The trouble with Sonos, in my view, is that the devices are great but let down by an awful App that frustrates and takes away the pleasure of building the system and knowing it will work. I have the Sub 4 in a non optimal place but it is working and sounds very good, much better than the Sub 3 which I had to return. My back ground is in networks and I know what to do and still find Sonos a challenge. Too bad really as the products are very well engineered.

Important Addition to the Sonos System

M Thomas from Parkville, MD on 2/15/2025

Verified customer (What's this?)
Verified employee review (What's this?)

As always, Sonos speakers give excellent sound quality. Sonos has improved on the connection process with the Sub 4. I had a Sub 2 and the sound/punch from the Sub 4 has significantly improved. This sub-woofer should be considered if you are looking to round out your Sonos System.

Pros: Great sound Easy connection

Cons: High cost

Sonos Sub 4

Allen from Manila, AR on 2/10/2025

Verified customer (What's this?)
Verified employee review (What's this?)

Love the little sub. I do have a Gen 3 one to go with it. I purchased this one because the loud end one was not enough. I play movies and regular TV at a lower volume now, and the one sub was insufficient. But after adding the second they work so well in tandem that they are heard without needing to crank I them up.

Pros: At low to medium volume, they are very good. Still can be heard at the higher levels but not window rattling.

Cons: Expensive for subs but they don't take up much space, and look nice out in the open. I prefer the look of Gen 3 but just my opinion.

A must with a Sonos Arc

Matthew from Concord, NC on 12/13/2024

Verified customer (What's this?)
Verified employee review (What's this?)

Huge sound and wonderfully balanced with Sonos Arc I have. The app setup was a little challenging, and I recommend to connect to 2.4G network, uses 5G for internal connection to arc. Crutchfield support was excellent and quick to answer my call. I probably could've used the sub mini for my size room, but when it rumbles i absolutely love it. It's really worth the money got on Black Friday sale and outlet open box ?? price. First Sonos products, really impressed.

Pros: Size, construction, balanced sound, able to control sub sound via app, really well built. Compliments Arc soundbar really well. Wireless connection to Arc.

Cons: App doesn't offer as many features as I'd wish for sub sound, like a test tone like my Yamaha system does. Setup can be a bit challenging.

Incredible Bass Performance - Game Changer!

Verified employee review (What's this?)

?????????? | Incredible Bass Performance - Game Changer! I recently added the Sonos Sub 4 to my home theater setup, and I couldn't be more impressed. The bass it produces is deep, powerful, and perfectly balanced, transforming my listening experience. Whether I'm watching action-packed movies or streaming music, the Sub 4 delivers room-shaking lows without distortion, even at high volumes. Setup was seamless through the Sonos app, and Trueplay tuning ensured the sub blended perfectly with my existing Sonos speakers. The design is sleek and modern, fitting well into my living space while looking like a piece of modern art. If you're on the fence about upgrading your sound system, the Sonos Sub 4 is worth every penny. It's a must-have for audiophiles and home theater enthusiasts. Highly recommend!
