Soundbars have evolved significantly, with models like the Sonos Arc Ultra showcasing advanced technology. Priced at 999 euros, it pairs well with the Sonos Sub 4, totaling 1,708 euros. While it offers superior features and sound quality, feedback highlights issues with the app and the performance of Sonos’ first headphones. The Arc Ultra stands out with its design, build quality, and innovative Trueplay calibration, delivering exceptional audio through its advanced components and Sound Motion technology.
When soundbars first emerged on the market, many were doubtful. How could a slender tube possibly replace a traditional speaker system with multiple components?
However, advancements in technology quickly silenced the naysayers. The pinnacle of this evolution is epitomized by top-tier models like the Sonos Arc Ultra, which we tested at a price point of 999 euros (RRP). We paired this impressive soundbar with the new Sonos Sub 4, priced at 899 euros (RRP). Together, these products set us back 1,708 euros during our test phase. Let’s dive into the key technical specifications of the Sonos Arc Ultra soundbar.
Though these features might suggest a ‘home cinema crown,’ it’s essential to remember that there’s always room for enhancement. This rings especially true in the realm of home cinema, where enthusiasts can invest tens of thousands of euros. Recently, Sonos has faced scrutiny from users, particularly regarding its app, which is crucial for product functionality. Additionally, their first headphones, the Sonos Ace, did not perform well in our assessments.
Comparing the Arc and Arc Ultra
The Sonos Arc has been a staple in the market for some time and remains available. Following the introduction of the Ultra, the manufacturer has reduced the Arc’s price by 250 euros, bringing it down to 750 euros. While this more affordable model offers 11 drivers compared to the Ultra’s 14, it supports only 5.1.2 sound rather than 7.1.2 and lacks the innovative Sound Motion technology. We will explore this unique Sonos technology further below. Unlike the Arc Ultra, the Arc also does not include a mechanical switch to disable its built-in microphones.
Aesthetics, Build Quality, and Setup
The design of the Sonos Arc Ultra aligns with typical soundbar aesthetics, featuring an elongated tube that houses the technology. The creative freedom in soundbar design is somewhat limited, with the exception of the unique Sonos Playbase. We wish there were bolder color options; the Arc Ultra is offered solely in black and white, identical to the subwoofer.
Keep in mind that the Arc Ultra, measuring around 1.18 meters in width, is best suited for larger TVs. While not a technical requirement, aesthetics matter, and it tends to overhang if paired with TV models smaller than 55 inches.
We were impressed by the build quality of the Arc Ultra. It feels incredibly robust and features rubber feet to secure it in place. Typically, it’s mounted on the wall just below the TV, and an optional wall mount is available from the manufacturer for 89 euros.
One feature we particularly enjoyed is the new volume slider located on top of the soundbar. This sensor strip is highly responsive, allowing for quick volume adjustments. You can also skip tracks using additional sensor buttons, along with a touch-sensitive play/pause option.
Connectivity, App Functionality, and Setup Process
The Sonos Arc Ultra is equipped with Bluetooth 5.3 and can connect to your home network via Wi-Fi or Ethernet. On the back, you will find the power connection, an HDMI eARC port, and the aforementioned switch for deactivating the built-in microphones. This feature is especially appreciated by those wary of the soundbar constantly listening, even though the switch is somewhat difficult to access as it’s located in a recess on the back. Keep in mind that with this feature turned on, you will lose access to voice control capabilities.
To enjoy TV audio or your favorite tunes, you’ll need to set up the Arc Ultra. As with most Sonos products, the manufacturer’s app—available for both Android and iOS—is essential for registration and setup. For our evaluation, we utilized the iOS app on an iPhone 16 Pro, and the installation was seamless. However, we did experience two crashes during our testing, but a quick restart resolved the issue.
Sonos Arc Ultra and Sub 4 in Daily Use
Alongside standard music control features, the Sonos app presents various fine-tuning options. Within the app, you can access an equalizer and modes that adjust sound dynamics (night mode) and enhance dialogue clarity in TV shows (speech enhancement). Both modes distinctly alter the audio experience. For those living in close quarters or apartments, the night mode is particularly beneficial, minimizing the impact of loud action scenes on surrounding neighbors and keeping your dishes intact even at higher volumes.
The Arc Ultra can be easily connected and synchronized with other Sonos products through the app, making it possible to create a comprehensive home cinema setup with recommended Sonos Era 300 speakers. Additionally, you can establish zones with other Sonos smart speakers in different rooms for seamless multi-room audio, allowing for synchronized or independent playback without latency.
Trueplay Calibration
Sonos doesn’t just release one soundbar each year. Recognizing that every placement is unique, the system must be calibrated to its specific environment. Previously, calibration required microphones; however, Sonos now utilizes the microphone in smartphones for this purpose, providing a clever solution.
During the ‘Trueplay’ calibration process, you’ll need to move around the room with your smartphone while the soundbar emits various sound effects. Don’t worry about what your neighbors might think—this calibration is vital for optimizing the soundbar’s performance and is surprisingly effective.
Technology and Listening Experience: Exceptional Sound from the Tube
It’s remarkable how much technology is crammed into this soundbar. The Sonos Arc Ultra boasts an impressive array of fifteen digital amplifiers, seven tweeters, and six mid-range drivers. These drivers are strategically positioned: forward for dialogue, sideways for soundstage, and upward for Dolby Atmos playback. Additionally, the innovative Sound Motion technology incorporates a dual-membrane subwoofer.
This technology is touted as one of the most significant advancements in sound technology in the last century, delivering unprecedented performance in a remarkably slim design that enhances clarity, depth, and balance.
For those who have experienced the Sonos Arc or own one, the Arc Ultra is claimed to provide ‘double the bass performance.’
