Our Verdict

Vizio V Series V51x-J6

Vizio SV510X-0806

The Vizio V Series V51x-J6 and the Vizio SV510X-0806 are both compact 5.1 soundbar setups. Overall, the 2024 Vizio SV510X-0806 offers a bit more bang for your buck due to its Atmos compatibility, improved surrounds performance, and ability to integrate with Vizio TVs. The older Vizio V Series V51x-J6 model features optical support, though, which is a bonus for older TV owners. Beyond this, there's not much to split the two when it comes to performance, so both are viable choices.
