Sub 4 - Wireless Subwoofer - Black

This is a truly impressive subwoofer. The review is linked to my experience with the Sub 4 and Arc Ultra. If you want a more in depth review please check out my experience with the Arc Ultra. Positives: Great looking with horizontal and vertical placement options, premium plastic materials and solid feel (in fact it’s quite heavy). It’s extremely stable with the force cancelling effect keeping it incredibly stable and vibration free for something as powerful as this. It’s insanely powerful especially in a smaller room and paired with the Arc Ultra. The bass reproduction is great and low end extension can reach as low as 25Hz and I can believe it. The rumble and effects it creates is amazing and really amps up the whole cinematic experience with the arc ultra. Music sounds fantastic with plenty of bass in the right frequency range and movies feel almost like in the cinema. You can hear and feel most explosions and low end effects with a real kick in my sofa and chest. For the insane amount of power and bass it has there are no reverbs or any issues with the sound reproduction. The internal design is quite something in the way they tunes it. Although it quite powerful it doesn’t overwhelm the bar with bass and better still you can adjust the volume and bass from the app. Connectivity is limited to WiFi and lan but works well with WiFi 5Ghz supported and unlike the arc ultra I had no issues connecting it first time. Negatives: It’s quite powerful so your neighbours might hate you:D It’s expensive and only works with other Sonos devices so must consider the option before buying. It’s recommended with the Arc Ultra and from my experience with this set up it’s a great pair albeit it very expensive one (definitely not for everyone’s budget). Not a negative for the Sub 4 but the Arc Ultra has insane levels of bass on its own so for some people it will make the Sub a harder choice. Final thoughts: When paired with the Sonos Arc Ultra this Sub 4 is just amazing and together they provide a true premium cinema experience in your home. If you are after some of the best sounding system in a fairly small package this is a great choice.

Well what can I say this unit is phenomenal, I entered the world of Sonos a week ago and it’s replaced my tv speakers and surround system, the quality and power that comes from this sub is amazing and connectivity and setup is a breeze. My only gripe is it’s expensive but your buying a premium sounding subwoofer, definitely recommend this to add to your Sonos system.

Excellent product, fits easily into the Sonos family, connection was a breeze and the sound is outstanding.

I purchased one along with the arc bar and two era 300 set up as a pair. Although the sub 4 lacks a little in power, the two era 300's produce some clear and punchy bass themselves. Once setup correctly, took me 3 days, and the sub 4 connects to the arc properly, it produces an epic sound for sure. Well done sonos 👌... ps. Can you make it a one touch connection?

Room shaking sound!! Such a good addition when added with soundbar. App lets you control every aspect really well too!

Yes the sub adds so much depf to my overall sound and makes the hole soundsystem come to life I so recommend this sub 4 to anyone that has a sonos sound system!

The best sound ever a great cinema experience in your own home no one could be disappointed!

I was so impressed with the sub adding it to my Arc and surround speakers. And when it works you can feel the sound. However I am not impressed when it can be a gamble that the speaker plays any sound, oh that will be because it needs updating , again. Or want to listen to music through all speakers not a chance. It is probably down to the App. But it is pain. And probably 50/50 that it works. So out of four speakers only the Arc works 100% of the time.
