Our Verdict

Polk Audio Signa S2

Samsung HW-T450

The Polk Audio Signa S2 is a slightly better performing 2.1 setup than the Samsung HW-T450. While both bars have a similarly bass-heavy sound profile, the Polk can get slightly louder but with more compression artifacts present. It also has an HDMI ARC input so it supports Dolby Digital, is center and surround performances are a bit better, and it has a dialogue enhancement feature. However, only the Samsung supports DTS via its Optical Audio In port.
