The popular Sonos subwoofer is now heavily discounted. It features two 6″ drivers and supports Wi-Fi

Sonos soundbars sound great on their own, but something is missing without a subwoofer. The Sonos Sub Mini is now available for 9,990 CZK instead of the original 12,990 CZK, which is a saving of 3,000 CZK compared to the regular price. It boasts two 6″ drivers and a frequency range starting from 25 Hz.

Quick Summary:
✅ Makes sense if you have a Sonos Beam, Ray, or Era 100 and want to significantly improve the bass component without cables.
⚠️ Consider carefully if you have a large room over 30 m² or need maximum volume – in that case, a full-fledged Sonos Sub is better.
💡 For 9,990 CZK, you get a premium subwoofer with wireless connectivity that adds to your soundbar in a minute, and a rating of 4.9 out of 5 speaks for itself.

Why this subwoofer is interesting

Sonos Sub Mini targets owners of Sonos Beam or Ray soundbars and Era 100/One speakers who want to significantly improve the bass component without the need for cables or complicated setup. The subwoofer connects to the system via 5GHz Wi-Fi, so you can place it anywhere in the room – only a power cable is needed.

The main benefit is that adding the subwoofer “relieves” the soundbar – it stops trying to play deep bass and can fully concentrate on mids and highs. The result is a cleaner and more balanced sound for the entire system, not just louder bass.

Technology and Construction

Inside the cylindrical enclosure are two opposing 6″ bass drivers. This design creates an effect of mutually canceling forces, which eliminates vibrations and distortion – in practice, this means your furniture or glasses in the cabinet won’t rattle. The subwoofer’s frequency extends from 25 Hz, covering even the deepest movie effects.

The dimensions of 30.3 × 22.8 × 22.8 cm are surprisingly compact – the subwoofer fits under a table or next to a sofa without taking up unnecessary space. The elegant cylindrical design in black or white will blend into most interiors.

Installation and Control

Setup is typically “Sonos-like” – you plug in the power, open the Sonos app, and you’re playing in a minute. The subwoofer automatically synchronizes with the soundbar, volume is adjusted together, and no complicated setup is needed. For advanced tuning, Trueplay technology uses an iPhone microphone to measure room acoustics and adapt the sound – however, it only works on iOS devices.

A practical feature is night mode, which dampens the bass for evening viewing so you don’t disturb neighbors. Control is done via the Sonos app, where you can adjust the bass level according to your preferences.

What Users Say

On Alza, the Sub Mini has a rating of 4.9 out of 5 (52 reviews) and 98% of customers recommend it. Over 1,000 units have been sold with a very low return rate (0.96%). These are numbers you don’t often see for audio products.

Reviewers repeatedly mention that the difference compared to the soundbar alone is dramatic – one user writes that “the experience of watching movies in Dolby Atmos subjectively improved by at least 50%”. Another compares the Sub Mini + Arc combination to “adding chocolate to your whiskey.” Praised are primarily clean, rich bass without rattling, elegant design, and easy installation. Several reviewers point out that even though the Sub Mini looks small, the sound is surprisingly powerful.

Critical voices are minimal. One user had temporary issues with the Sonos S2 app, which were later fixed. Someone mentions higher power consumption in standby mode, and of course, there’s also a reservation about the price – although most reviewers conclude that the quality matches it.

When it doesn’t make sense

If you have a large room over 30 m² or want maximum performance for parties and high volumes, the Sub Mini might not be enough – in that case, look at the full-fledged Sonos Sub. Also, if you don’t own any Sonos product, the subwoofer alone will be useless to you – it only works in combination with compatible soundbars or speakers. And if you use Android and want Trueplay calibration, you’ll need an iPhone or iPad.

If this particular model didn’t appeal to you, but you’re looking for audio on sale, you can browse current Alza Days, where other discounted products continuously appear.

Verdict: Who it’s worth it for

The Sonos Sub Mini for 9,990 CZK is an ideal addition for owners of Sonos Beam, Ray, or Era 100/One speakers in small to medium-sized rooms. Wireless connectivity, simple installation, and a rating of 4.9 out of 5 speak clearly. However, keep in mind that for large spaces or maximum performance, it’s better to opt for the larger Sonos Sub – but that costs more than double.

Do you have a Sonos soundbar at home? Have you added a subwoofer to it, or is it enough on its own?
