Excerpt: The center speaker is the most important element of a home theater sound system. Getting a high-quality center speaker, like the Polk Audio CSi A4 , ensures that dialogue and lyrics won't be drowned out by background noise or sound effects. It has a compact design and is lighter than many of the other center channel speakers we reviewed. It is for these reasons that we found the CSi A4 to be one of the top ten best center channel home theater speakers in our review.
Pros: The 2-way Polk Audio CSi A4 center speaker can play a wide range of frequencies.
Cons: It has a lower sensitivity level than many other speakers in our review.
