The Sonos Sub (Gen 3) and the Sonos Sub Mini are the brand’s options when it comes to subwoofers. We compare the two below to help you decide which one is better suited to your preferences and needs.

Size is the biggest difference between the Sonos Sub Mini and Sonos Sub (Gen 3).

Sonos speakers have minimalistic, elegant and modern designs. The Sonos Sub Mini and Sonos Sub (Gen 3) stay true to those design choices. Both the Sonos Sub Mini and Sonos Sub (Gen 3) feature a simplistic design with inward facing drivers for both style and function. They have cutouts in the middle of their enclosures that make them instantly recognizable. The Sonos Sub Mini and Sonos Sub are both available in black or white, but the former has a matte finish while the latter is glossy.

Size is where the biggest difference between the two lie. Measuring 12 inches tall and 9.1 inches in diameter, the Sonos Sub Mini is significantly smaller than the Sonos Sub (Gen 3), which measures 15.3 x 15.8 x 6.2 inches. Needless to say, the smaller footprint of the Sonos Sub Mini lends it easier room placement.

Another difference is with their weight, with the Sonos Sub Mini weighing significantly less. It weighs 14lbs, which is half of the Sonos Sub (Gen 3), which weighs 29lbs. As the more compact and lightweight subwoofer, the Sonos Sub Mini is easier to relocate and set up.


They have similar features, but the Sonos Sub can work in tandem with another Sonos Sub, while the Sonos Sub Mini is limited to only one.

Due to their wireless nature, both the Sonos Sub Mini (left) and Sonos Sub (right) can be placed anywhere (with a nearby power outlet).

Features-wise, the two subwoofers are similar in that they both have WiFi connectivity and one button pairing, plus they work with the Sonos App and support Trueplay room correction. The Sonos App has an NFC button for instant pairing and it also has EQ settings for you to adjust the volume, treble and bass. That said, both subwoofers will automatically adjust the volume to match the paired speakers or soundbar.

Trueplay room correction is a nice feature if you want the speaker system to adjust its output based on the acoustics of your room. However, Trueplay is only available on iOS, so if you have an Android phone, you won’t be able to have access to it.

One feature that’s exclusive to the Sonos Sub (Gen 3) is that it can be paired with another Sonos Sub for a multiple subwoofer setup. This is a nice feature to have if you have a large dedicated home theater room. With dual/multiple subwoofers, the bass response can be improved tremendously.


The more compact Sonos Sub Mini is better for smaller rooms while the larger Sonos Sub (Gen 3) is better suited for medium to large rooms.

Both subwoofers are equipped with two class-D amplifiers with dual woofers. These woofers are placed opposite of each other, which is why there’s a cutout in the middle. This design choice eliminates buzz and cabinet rattle for optimal performance.

The two subwoofers can go down to 25Hz, at least according to their spec sheets. There’s not much information about the subwoofers’ amplification, but it’s safe to assume that based on their sizes, the Sonos Sub (Gen 3) is the more powerful unit.

As for sound quality, both offer exceptional bass performance as long as they are placed in ideal situations. The Sonos Sub Mini, which is the smaller subwoofer, is ideal for smaller rooms or if you tend to watch movies or listen to music at low volume. If space is a major factor, the Sonos Sub Mini is definitely the better option.

The size of the Sonos Sub (Gen 3) is better suited for larger spaces. It still performs excellently in smaller spaces, but it can be a bit overkill. The Sonos Sub (Gen 3) is designed for dedicated home theater rooms or living spaces with a large area.


The Sonos Sub Mini is perfect for those with smaller homes or home theater rooms while the Sonos Sub (Gen 3) provides more power for those with larger homes or home theaters.
