Over the past few months, numerous details and photographs have leaked of what appears to be Sonos' next flagship soundbar, the long-awaited Sonos Arc Ultra. This device has generated, from the beginning, a lot of expectation due to the technological improvements that it promises to incorporate and its possible impact on the home theater sound market. The first leaks appeared a few weeks ago on X (previously known as Twitter) with the person in charge of providing this information being the well-known leaker @MysteryLupin, who has a history of success with technology products that have not yet been launched. Well, it seems that the bar is closer than ever, since it was the manufacturer's own website that revealed it.
New Sonos Arc Ultra
Aesthetically, there will be no major changes, as it will practically be the same sound bar that we can currently find in the brand's catalogue. The interesting thing will be inside, as the new Sonos ARc Ultra will feature very striking technologies that will further improve the spectacular sound that the previous model offered us.
Among the main novelties, the inclusion of technology stands out Sound Motion. This advancement promises to take surround sound a step further, optimizing the way sound interacts with the space of the room, offering an even more immersive experience. In the words of those who have analyzed the leaked information, the Arc Ultra could redefine the home cinema experience, providing three-dimensional sound that completely envelops the viewer (yes, this is something that is always repeated in these cases, but it seems that on this occasion it will be something quite remarkable).

Additionally, according to screenshots shared on Reddit and other forums, it has been revealed that this new soundbar will have a total of 14 custom drivers. These components, designed by Sonos, would be strategically arranged to maximize the quality and amplitude of the sound emitted, this being the key to performance. The audio configuration Dolby Atmos 9.1.4 will allow a 360º listening experience, making the Arc Ultra an extremely powerful surround sound system.
Bluetooth and new connectivity features

Another important detail to highlight is the addition of Bluetooth, a feature that was not available on the current Sonos Arc. Bluetooth integration not only opens the door to a wider range of connectivity options, but also makes it easier to pair mobile devices more easily.
This upgrade has been welcomed by experts and enthusiasts alike. Until now, Sonos soundbar connectivity was limited to Wi-Fi. However, the addition of Bluetooth means that the Arc Ultra will be compatible with a wider range of devices, thus expanding its functionality.
Other small changes to the physical controls have also been mentioned. The latest leaked photos show more refined and better positioned buttons to make handling the device easier. The power key, for example, has been moved to the far left, while the volume controls are now located on the right side.
Sub 4: The perfect complement to the Arc Ultra
While most of the attention is centered around the Arc Ultra, it's not the only new thing Sonos could be cooking up. According to leaks, the company is also reportedly launching a new subwoofer called the Arc Ultra. Under 4, which would perfectly complement the audio experience of the Arc Ultra.
The leaked images of this device show a robust and minimalist design, very much in line with the brand's other products. Also available in matte black and white finishes, the Under 4 would be the successor of the current one Under 3It is speculated that this new subwoofer would incorporate two force-cancelling woofers, allowing for more powerful and precise bass.
At the moment, the leaked price of this accessory is around $799, a considerable figure that places it in the premium range of sound devices. Together with the Arc Ultra, both products are positioned as a reference option in the sound bar and subwoofer market.
Sonos Arc Ultra Price and Availability
The price of the Sonos Arc Ultra has generated a lot of debate. Taking into account the screenshot taken from the official Sonos website (product already discontinued) the price would rise to $1.199. It is a very similar price to that of the current model, although slightly higher. In Europe, the conversion to euros would place the price of the Arc Ultra between 950 and 1.250 euros, depending on the market. It should be noted that Sonos has not yet offered any official confirmation on these prices, leaving room for speculation.
As for availability, although there is no official release date, rumors and leaks suggest that the presentation could be imminentSome sources even mention that Sonos has had to delay the announcement of the Arc Ultra due to recent problems with its mobile app, which has caused frustration for many of its users. We'll have to see if the announcements happen soon, as everything points to them being closer than they seem.
