Our Verdict

LG SL6Y

Samsung HW-A450

Depending on your listening habits, you may prefer either the LG SL6Y or the Samsung HW-A450. The LG is a 3.1 setup that's better built with better center and surround performances. It also comes with HDMI ports, unlike the Samsung soundbar. That said, the 2.1 Samsung can reproduce a more extended low-bass.
