The Sonos Era 100 retails for $219 new, but you can pick up a certified refurbished model for just $134. This is Sonos' most popular and most versatile speaker. Despite its compact size, the Era 100 houses two tweeters, a mid-woofer, and three class-D digital amplifiers to produce precise, distortion-free audio even at high volumes. It has a built-in microphone for smart functionality. Because of its flexibility, it's often paired with a sound bar or a second Era speaker.

Sonos Arc Soundbar

Sonos doesn't discount its flagship Arc lineup of speakers very often, so it's a wise investment to jump on a good sale when you see one. The Sonos Arc was discontinued last year to make way for its successor, the Arc Ultra. The release of the Arc Ultra doesn't make the Arc any less of an outstanding speaker. It's a better value than picking up the Arc Ultra, currently not on sale for $1,100.

The 45" soundbar houses eleven precisely engineered internal speakers, including three tweeters and eight midwoofers each paired with Class-D amplifiers. It's capable of room filling audio by itself, but you'd still benefit from a separate subwoofer to round out the low end. Unlike the Sonos Beam, which only has virtual height channels, the Arc has two physical height channels for true Dolby Atmos support. The Arc also has a built-in microphone.

Sonos Beam (Gen 2) Soundbar

The Sonos Beam is a great option for someone who requires a more compact sound bar or simply doesn't want to spend too much money on a speaker system. It's attractively priced right now at just $299, so $100 less than the Arc. The Beam (Gen 2) is a 26-inch long, 5.0-channel soundbar with one tweeter and four mid-woofers for natural, balanced sound and four passive radiators to help with the low end. Although the Beam doesn't have physical height channels, it has two virtual height channels for Dolby Atmos support. There's also a built-in microphone for smart functionality.

Sonos Sub 3 Subwoofer

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. If you want to add ground-shaking bass to your Sonos setup, there's still nothing better than a separate standalone subwoofer. The Sub 3 boasts plenty of power in the form of dual inward-facing 5"x8" woofers and a ported design that allows for a louder and deeper low-end.

Why Sonos?

If you're looking for an easy solution to add great sound to your home, then you've probably already heard of Sonos. Sonos speakers are very easy to set up, don't take a large amount of space, and most importantly, offer distortion-free room-filling audio. They're definitely pricier than budget options, but the sound quality is comparable to speakers that cost hundreds more or take up much more space.
