SonosSub 4 - Wireless Subwoofer - 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.

Excellent, the value was great, it has excellent quality and acoustics.

Sound quality is top notch! Design looks great, especially all white! Was easy to set-up.

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!

Sounds amazing, just had to do a lot of setup procedures.

Works well augmenting soundbar.

Really strong bass with clear sound! Really boosts the performance when coupled with the 300 speakers.

Great quality and amazing sound but took awhile to set up and had to repair my sonos beam, which I was trying to sync it up with, just to get it to work. But after that, I have not had any issues neither connection or quality wise.
