Our Verdict

Denon Home Sound Bar 550

LG SP9YA

The LG SP9YA is better than the Denon Home Sound Bar 550. The LG is a 5.1.2 setup with a dedicated subwoofer that can reproduce a more extended low-bass. It has better soundstage and center performances, and it gets louder with less compression at max volume. Also, it offers more sound enhancement features, including room correction.
