Our Verdict
Polk Audio Signa S2
Yamaha YAS-209
The Yamaha YAS-209 is a much better soundbar than the Polk Audio Signa S2. The Yamaha has a better-balanced frequency response and performs better with music. However, it doesn't get as loud as the Polk, but it performs way better at max volume. It also has a lot more inputs and supports more audio formats, on top of being able to play content via Wi-Fi.
