Sonos Soundbars: Arc vs. Beam

The Arc is a new premium smart soundbar from Sonos. So, how does it compare to the older Sonos Beam?

You can find out in this comparison guide.

Quick Summary

If you want the best and most powerful soundbar, then we recommend getting the Sonos Arc as it comes with more digital amplifiers, tweeters and woofers than the Sonos Beam.

With that said, the Sonos Beam is more affordable. If you have a smaller room and/or on a tight budget, then you might want to get the Beam over the Arc.
