Sonos, a leading name in premium audio, is currently offering a significant discount on its flagship Arc Ultra soundbar. The white version of the Sonos Arc Ultra is now available for 19,990 Kč, a reduction of nearly 3,500 Kč from its typical price and close to the lowest price ever offered on Alza. Notably, the black model is listed at 22,490 Kč, making the white version 2,500 Kč more affordable.
Quick Capture:
✅ It makes sense if you’re looking for a soundbar with truly immersive Dolby Atmos sound and want to avoid the complexities of a traditional home theater setup.
⚠️ Consider if you prefer the black color (which costs 2,500 Kč more) or if you expect deep bass without purchasing a subwoofer.
💡 At 19,990 Kč, you’re getting a flagship model with Sound Motion™ technology and a What Hi-Fi? Award – an exceptional offer at this price point.
Why This Soundbar Is Notable
The Sonos Arc Ultra is designed for users who want a cinematic sound experience without the require to install multiple speakers throughout a room. This flagship Sonos model features an entirely new acoustic architecture, powered by 14 drivers including the Sound Motion™ bass driver, which the company says delivers twice the bass performance of the previous Arc generation. The result is a 9.1.4 Dolby Atmos spatial audio experience that envelops listeners without requiring rear speakers – a growing trend in simplifying home entertainment setups.
The Arc Ultra has received the What Hi-Fi? Award, a respected recognition in the soundbar category. Unlike more affordable models, it also offers AI-powered speech enhancement with four adjustable levels – particularly useful for films with quiet dialogue and loud effects.
Key Parameters in Practice
Sound Motion™ technology is the primary innovation over the older Arc model. It features a special bass driver with four motors and two membranes in a compact design, allowing for deeper bass without the need for an external subwoofer. In practice, this means that for typical movie and TV viewing, a Sub isn’t necessary – users report surprisingly powerful bass even without one. However, for truly deep frequencies (action movies, music with strong bass lines), a subwoofer will still enhance the experience.
The soundbar supports Dolby Atmos, Dolby TrueHD, Dolby Digital Plus and DTS Digital Surround. To fully experience Dolby Atmos, a connection via HDMI eARC and proper settings on both the TV and streaming box for passthrough are required – some users in reviews note that it takes some time to learn, but then everything works reliably.
Practical Considerations: Connectivity, Control, Dimensions
The Arc Ultra connects via HDMI eARC (a cable is included) and supports Wi-Fi 6, Bluetooth 5.3, and Apple AirPlay 2. It can be controlled with your TV remote, touch controls on the soundbar itself, or through the Sonos app for iOS and Android. The app also offers a Trueplay™ function that measures the acoustics of the room and automatically adjusts the sound based on the soundbar’s placement.
Dimensions are 1,178 × 75 × 110.6 mm with a weight of 5.9 kg – the soundbar is relatively wide and best suited for televisions 55” and larger. A wall mount is not included and is sold separately for approximately 2,290 Kč, which some users have noted in reviews. The design features a matte white, curved shape that most reviewers describe as elegant and understated.
What Users Are Saying
On Alza, the Arc Ultra has a rating of 4.8 out of 5 (based on 60 reviews) and 93% of customers recommend it. The reported defect rate is very low – just 0.79%. Users most frequently praise the clarity of the sound, the immersive Dolby Atmos effect, the surprisingly powerful bass even without a subwoofer, and the easy integration into the Sonos ecosystem. Several reviews mention that the difference from the older Arc is noticeable, particularly in dynamics and bass depth.
Critical feedback primarily focuses on details: the wall mount is not included in the package, the Sonos app occasionally has issues (especially when connected to Apple Music), and some users expected even deeper bass without a subwoofer. One reviewer points out that if you already own an older Arc with Era 300 and Sub, the upgrade to Arc Ultra may not be as significant as expected. However, for most users upgrading from less expensive soundbars, the difference is described as “worlds apart” in reviews.
When It Might Not Be the Right Choice
If you’re looking for a soundbar on a tighter budget, the Arc Ultra, with a price of almost 20,000 Kč, isn’t the right option – Sonos offers the more affordable Beam (Gen 2) around 10–11 thousand Kč or the Ray for under 6 thousand Kč. Similarly, if you don’t need Dolby Atmos and are satisfied with solid stereo sound for your TV, you’ll be paying for features you won’t use. And if you prefer black, you’ll pay an extra 2,500 Kč – in that case, it’s worth considering whether the white version will be distracting.
Verdict: Who Should Buy It
For 19,990 Kč, you get a flagship soundbar with Sound Motion™ technology, 9.1.4 Dolby Atmos, 14 drivers, and a What Hi-Fi? Award. If you want a truly immersive spatial audio experience without installing multiple speakers and don’t mind the white color, the Sonos Arc Ultra is hard to beat at this price.
