Sonos finally introduces the small subwoofer everyone has been waiting for

Sonos has taken its time, but now the time has come: The Sub Mini is a small Wi-Fi subwoofer for the One, Beam, and Ray. We present the speaker and its technical specifications.

Sonos Sub Mini: A compact subwoofer for small rooms

The Sub Mini does exactly what the name promises: The cylindrical bass speaker is extremely compact. With a diameter of just 23 cm and a height of 30.5 cm, the Sonos Sub Mini is much smaller than the Sonos Sub (check it out at MediaMarkt) and, at 6.35 kg, it’s also much lighter. The Sub Mini is designed to help smaller Sonos speakers like the One (SL), Ikea Symfonisk bookshelf speakers, or the Ray and Beam soundbars with low frequencies.

Consisting of a closed cabinet (no bass reflex port), the Sub Mini uses two inward-firing force-canceling woofers. The Californian audio specialist promises a “dynamic reproduction of the low frequencies without clatter and rattle”. As is often the case, digital signal processing is involved: the music signal is analyzed shortly before playback and the speaker’s performance is optimized accordingly. In addition, the proven room optimization (“Sonos Trueplay”) is also provided, for which the room is measured with a supported iOS device (e.g. iPhone) while test signals are played. This should also keep acoustically “difficult” rooms with unwanted reflections in check.

As usual with Sonos, the integration is done via app, it is a subwoofer that hooks wirelessly into the existing setup. This can take place in terms of music playback (e.g. two One and a Sub Mini) as well as in a home theater scenario. One limitation here is that only one Sub Mini is provided per room. Two of the larger Sub (without the “Mini”) can also be integrated for a particularly large home theater.

The Sub Mini fills a gap in the line-up

It has been a justified point of criticism for years: If you wanted to add a subwoofer to your Sonos multi-room setup, you had to reach for the only model available so far, the Sonos Sub. However, quite a few customers find the WLAN bass speaker too big and too expensive: Why put an 800-euro speaker in a small bedroom that is actually intended for much larger rooms? Something more compact and less expensive was needed. Now, finally, the redemption – even though the price of just under 500 Euros for the Sonos Sub Mini seems a bit high to me. Is the quite small case volume sufficient to provide rich bass? A detailed practical test will have to show that. I will soon test the Sub Mini in combination with Sonos One and Sonos Ray.
