    • This subwoofer provides high quality bass to augment your other Sonos products
Color: Black
If you're looking to add wireless speakers, etc. to your TV or other entertainment devices, Sonos is the way to go. Sonos is quite expensive, but you're buying not only high-quality audio devices but also the flexibility of being wireless for sound and the interconnectedness of all the Sonos devices. The Sonos app recognizes all of your various devices and makes it easy for them to work together. You can assign devices to specific rooms or, if you want, set up a home audio network where music is played everywhere. The Sonos app also integrates access to Apple Music, Amazon Music, or just the Sonos music that they offer. For a home theater, starting with a Sonos soundbar opens the door for adding other Sonos speakers and a Sonos subwoofer. The sound bar, while using the Sonos application on your smartphone, will recognize other speakers and a subwoofer in the room. You also can configure the speakers to work separately, or they can be part of a surround sound system tied to the Sonos sound bar. The nice thing about each of the system audio components is that individually, you can touch the component (a speaker or soundbar for example) and control the room sound level, so you don't always have to go to the Sonos app on your smartphone to do so. You can get great sound for your entertainment system without requiring a receiver and complicated wiring. Generally, you just need: • A power cable • An HDMI cable for connecting to a TV • Preferably an Ethernet cable so all the devices can work over your Wi-Fi network • The Sonos subwoofer can work wirelessly, without requiring an Ethernet cable connection which is optional ... show more

    • ⭐️⭐️⭐️⭐️⭐️ Deep, Room-Shaking Bass That Completes the Arc Ultra
Color: White
I paired the Sonos Sub 4 with my Arc Ultra soundbar, and the difference is unbelievable. The dual Sonos-engineered drivers produce bass that’s not just deep, but clean and powerful—no distortion, no buzz, just rich low end that you can feel as much as hear. The ported enclosure really brings out those low frequencies, making movies, games, and music incredibly immersive. The force-canceling acoustic design works exactly as promised—I can push the volume and still get distortion-free bass. Setup couldn’t be easier: plug in the power, connect through the Sonos app, and it’s ready to go. I love the flexibility too—you can stand it up or lay it flat to tuck it under a sofa. Combined with the Arc Ultra, this setup truly transforms your living room into a theater. Add one Sub and you’ll be amazed; add two and you’re in for a mind-blowing experience. The sleek matte finish and sculptural design also make it a showpiece rather than something you’d want to hide. If you own an Arc Ultra, the Sub 4 is an absolute must-have. Together, they deliver cinematic sound that rivals high-end theaters right in your home. ... show more

    • THE BEST JUST DO IT

Buy 2 - if you are looking at this then you are serious about a great home theater setup - these aren’t cheap - but get two and thank me later. So easy to set up. The true-play is awesome - just do it.

    • Used and works perfectly.
Color: Black
I purchased this used, and the condition was refreshingly honest. It was basically perfect, but for a few light scratches on the top (I guess it was used as a small table?). They can only be seen if the light is just right, and the eyes are close. I put a mat over it anyway (so I can use it as a table too!). Well worth the savings for a great-quality and condition used item. ... show more

    • Best upgrade to your soundbar
Color: Black
Review Image by JMK JMK
The media could not be loaded. Great upgrade to your Sonos Arc Ultra. I bought mine after the purchase of my Sonos Arc Ultra… I never knew what I was missing out on all these years from my old setup. My square footage is about 260 sqft. I was afraid it would be too big for my space. I’m glad I didn’t go with the mini sub. The setup was so easy and sound quality is perfect for my space. It functions as its designed, and speaking of look it doesn’t stand out as an awkward afterthought. ... show more
