What comes immediately to mind when we say the term subwoofer? Is there a rumbling box in the corner of the room as the dinosaur pads across the earth onscreen? Or the thing that rattles automobile door panels at stoplights? Neither of them, it may be argued, has much to do with “music.”

Today we will review Sonos Sub Gen 2 vs Gen 3 and see their differences. If you are interested in these models, keep reading our Sonos Sub Gen 2 vs Gen 3 review for more information below.

Winner of Sonos Sub Gen 2 vs Gen 3: Gen 3

The third version of the Sonos Sub is now available, and with the exception of a few small aesthetic modifications, it is nearly identical to its predecessors. The size, shape, and construction concept are same, and the maker claims that there is no variation in sound quality or performance.

The primary improvements are found on the inside: the new Sonos sub has a quicker CPU and more internal memory than its predecessors, making it more responsive to future features and updates.

Sonos Sub Gen 2

Description: The Sub Gen 2 is intended to work with an existing Sonos setup, which is one of the most popular multiroom music systems on the market.

Features: The Sub Gen 2 is a big subwoofer with an O shape that is roughly the size of a PC tower. Two oval, 6-inch drivers are arranged in a push-pull configuration in the middle of the device, which Sonos claims prevents cabinet shaking.

The cabinet weighs 36.3 pounds and is coated in a glossy black lacquer; it’s a great-looking piece. The business is reportedly preparing a non-glossy version later this year (for $100 cheaper), which we welcome because the black finish doesn’t match any of the other Sonos components.


  • The Sonos Sub has an eye-catching appearance and operates wirelessly from anywhere in the room
  • It improves the quality of your Play speakers and is simple to set up


  • Needs to be plugged in

Sonos Sub Gen 3

Description: Perhaps the most intriguing new feature of the Sub Gen 3 is one that bass-obsessed Sonos fans have been requesting for years: the option to install an additional subwoofer in the same room.  

Features: Additional subwoofer installation may be done in conjunction with an earlier Sonos Sub, requiring only one 3rd generation Sub. The Sonos subwoofer is a small and portable device. It may be installed either upright or flat under the sofa. Wall installation is also available if you purchase an additional wall bracket.

If you already have a Sonos system, just connect in the power, open the Sonos app, and add the subwoofer to your current system.

A music subwoofer differs from a home-theater subwoofer in that you seek punch and speed above sheer bowel-shaking depth. Some (expensive) subs can handle both duties, but the majority can only perform one well. Not unexpectedly, the Sub is incapable of making your trousers flap, but it does provide a fair amount of punchiness.


  • Double Sonos bass
  • More flexible
  • Worth the cost


  • None

Sonos Sub Gen 2 vs Gen 3 Comparison

Many people will undoubtedly note that the Sub Gen 3 appears identical to its two predecessors. But, when all of its little improvements are considered, it’s evident that there’s more to the Sonos Sub Gen 3 than meets the eye according to our Sonos Sub Gen 2 vs Gen 3 review.

The following are the external differences. For a sleeker, more ergonomic look, the pairing button has been contoured and integrated into the Sub’s cabinet. The flat power cord to reduce tangling with other wires.

The major distinctions, however, are found on the inside: Memory and processing capability are increased owing to 256 MB of RAM and a 1 GHz CPU. Internals are compatible with the Sonos S2 for usage with the new Sonos control platform. High-powered radio receiver for improved range and communication. BLE (Bluetooth Low Energy) and NFC (Near Field Communication) for a simpler and quicker setup.

In the case of the Sonos Sub Gen 3, all of the aforementioned changes are minor enhancements that make this wireless subwoofer even better than before.

But, as the old adage goes, “if it ain’t busted, don’t repair it,” and Sonos has adhered to this principle by ensuring that the best parts of the Gen 2 model are carried over into the Sub Gen 3.

For those of you who are unfamiliar with the Sonos Sub, this wireless subwoofer will improve the bass response of any Sonos home theater system or Sonos speaker save the Sonos Move.

The Sonos Sub Gen 3 boasts two Class-D digital amplifiers that are calibrated to drive two face-to-face, force-canceling speakers to create powerful bass that you not only hear but also feel.

As a consequence, the subwoofer has a clean bass response that is both powerful and dramatic, as well as an acoustically engineered cabinet that eliminates the buzz and rattling that is typically associated with subwoofers with poor cabinet construction. So, not only does the Sonos Sub’s cabinet make it look attractive, but its meticulous design also makes it sound great.

The Sonos Sub (Gen 3) is a certain method to improve your surround sound experience and is now available with the new Sonos Arc and Sonos Five.

Conclusion: Sonos Sub Gen 2 vs Gen 3 [2022 Review]

If you’re a die-hard Sonos fan and your Play:3 or Play:5 speakers aren’t providing enough bass weight, the Sub will make a noticeable difference in your system. It will clean up the whole sound spectrum and offer your system bass control as you’ve never experienced before.

The Sub, on the other hand, is almost too amazing to be paired with the current speakers. Could Sonos be working on a suitable stereo system to go along with it? Absolutely! We hope you liked our Sonos Sub Gen 2 vs Gen 3 review and it was helpful.
