Our Verdict
Samsung HW-B450
Samsung HW-B550
The Samsung HW-B550 is better than the Samsung HW-B450. They're both 2.1 soundbars that offer similar stereo frequency responses, but the B550 comes with some extra features. It's better built and has a graphic EQ, so you have more ability to customize its sound. There are also HDMI connections, which the B450 lacks. If you aren't interested in these features, though, the B450 is pretty similar, and it's more affordable overall.
