Our Verdict

Yamaha YAS-209

Polk Audio Signa S4

Depending on your listening habits, you may prefer either the Polk Audio Signa S4 or the Yamaha YAS-209. The Polk is a 3.1.2 setup that supports Dolby Atmos content, unlike the Yamaha. It also has a better center channel performance. However, the Yamaha reproduces a more extended low bass. It also supports DTS content and has a Full HDMI In port, unlike the Polk.
