Our Verdict
JBL Bar 5.1 Surround
Vizio M Series M51a-H6
The Vizio M Series M51a-H6 is better than the JBL Bar 5.1 Surround. The Vizio comes with dedicated satellites and supports Dolby Atmos content. It gets louder with less compression at max volume and has better soundstage and surround performances. That said, the JBL is better built and has more wireless playback options.
