    This is our second Sub Mini and we couldn’t be happier. These little guys punch way above their weight class and integrate flawlessly into the Sonos ecosystem. Ours stays nicely hidden underneath the kitchen sink and is paired to two Sonance in ceiling speakers to round out the room. Highly recommend!

    This little guy makes my home theater setup complete. It is excellent for subtle and also ground rumbling bass. Explosions rattle my wife’s trinkets lol.

    The mini is perfect for my smaller living room, but the smaller size doesn’t keep it from throwing out some serious bass. It was super easy to add to the Sonos app and connected with my Arc and LG TV immediately. I love it.

    I purchased the Sonos One SL about 2 years ago, and was floored at how good it sounded by itself. The only thing for me that could be better, was low end. I’ve always wanted this sub and finally purchased it and it has fully rounded off the bottom end and again, blew me away. Truly awesome.

    Sub 4 is a powerhouse addition to my Sonos arc ultra. Its deep, rumbling bass adds incredible depth to music and movies without distortion, even at high volumes.

    Excellent power and bass for such a small size package that can be tucked away in a corner and forgotten about. Pairs so well with the Arc for a total listening package. A must have if you have the budget to buy both as it really makes a noticable difference. Reliable wireless connection as well and happy to report I haven't run into any issues a year later.

    This sub is one of 4 Sonos products I have. The bass is clear and shakes the room at low volumes. I usually have my sub set at -3. And it goes to +15.

    Great subwoofer especially for a pair of sonos ear 100. Love how easy it is to connect the sub. The sub mini sounds great especially against a wall. It also just has the power cable so no need for extra cables. It does connect through wifi so make surr it connected to the same one as your other sonos speakers.
