Sonos currently has a President's Day Sale going on right now that takes up to 20% off sitewide, including a $200 discount on the Arc Ultra that drops it to $899. However, if that's still a bit rich for your blood, there's an even better going on right now. The certified refurbished Sonos Arc has just dropped in price to $449 with free delivery. That's half the price compared to getting the Arc Ultra on sale and an excellent deal for anyone looking for a Dolby Atmos capable soundbar.
Sonos refurbished products go through rigorous testing; they come with all accessories, manuals, and documentation and are reshipped in "pristine" packaging. Most importantly, Sonos includes the same 1-year warranty as buying new.
Sonos Arc Soundbar (Refurbished)
The audio savvy knows that a single speaker isn't enough to reproduce an entire soundstage. If you could pick only one other speaker to supplement your existing one, then a subwoofer would make the most meaningful impact.
