I had a chance to test and compare two models: Polk Audio Command Bar vs Klipsch Cinema 600 and this review should help people who are looking for a good soundbar. The Polk Audio Command Bar was rated 6.6, while the Klipsch Cinema 600 has a rating 4.8.
Each of the models under consideration has active amplification type. A noticeable difference is the number of channels that Command Bar has 2.1 and Cinema 600 has 3.1.
