Our Verdict
Yamaha YAS-207
Polk Audio Signa S2
The Yamaha YAS-207 is a better 2.1 soundbar than the Polk Audio Signa S2. The Yamaha's sound profile is better balanced and is suitable for a wider range of stereo content. Its subwoofer also creates deeper bass, and the bar creates a better overall phantom center channel. It also features a bit more inputs like a Full HDMI In port. On the other hand, the Polk isn't entirely covered by mesh and feels a bit more durable.
