Our Verdict

Vizio M Series Elevate M512E-K6

Vizio Elevate SE SL512X-0806

The Vizio Elevate SE SL512X-0806 is a slightly more affordable soundbar than the Vizio M Series Elevate M512E-K6. But don't let that fool you. These soundbars perform very similarly across the board. They share a design language, and the various speakers are all similar in size. You can expect broadly comparable audio performance from either set. You'll mostly find the upgrade to the M512E-K6 worth it if you absolutely need video passthrough, a full HDMI input port (rather than just an eARC port), or a physical remote.
