Plus an upgraded Sonos Sub promises an impressive home theatre system.

I've been hanging out for this announcement since I got to test the original Sonos Arc while reviewing the Sonos Ace headphones. Sonos has announced the impending arrival of its new Arc Ultra soundbar, alongside the updated Sub 4 subwoofer.

Information on the new soundbar has been leaking like crazy for months, so it's great to see the actual announcement happen.

The new Sonos Arc Ultra promises to deliver clearer dialogue, deeper bass and more detail. It does this through a technology it calls Sound Motion, which allows for significantly smaller transducers while delivering much deeper bass.
