The Sonos Arc Ultra soundbar will deliver 9.1.4 channels of Dolby Atmos sound from 14 drivers that include Sonos' new Sound Motion speaker tech – plus Trueplay tuning for Android, and a new adjustable voice enhancement feature.

That's all according to the latest big leak, this time from US retailer B&H Photo Video, which posted an article about the launch, presumably a little early as part of the retailer's pre-launch prep. (This was spotted by the ever-vigilant r/sonos subreddit.)

This makes me think the soundbar is seriously imminent, perhaps even launching today, though we're expecting a release date of October 29th based on the previous leak.

I'll go through what's in the leak just below, but first here's a teaser video placed (and then seemingly removed) from Facebook to really get you in the Arc mood.

The key new Arc Ultra leaks explained

The leak once again confirmed that we're expecting the Arc Ultra and Sonos Sub 4 to launch alongside each other, but contains a load of information we didn't have before.

First and foremost is the speaker setup. Here's what B&H Photo Video has to say about it:

"The Arc Ultra houses a whopping fourteen drivers—three more than the Arc—consisting of seven tweeters, six midwoofers, and a built-in subwoofer. Each driver, engineered by Sonos, is precisely placed and angled within the soundbar to deliver 9.1.4 channels of sound all on its own. Fifteen class-D digital amplifiers, perfectly tuned to the soundbar’s unique acoustic architecture, power each driver individually to optimize the sound for every channel."
