How can I boost the center channel in my sound bar?

Episode 1109 (1:11:41)

Steve from Mill Valley, CA
Pioneer Andrew Jones 5.1 sound bar

Steve has a sound bar and wants to boost the center channel. Leo says that he would have to have Dolby 5.1 to be able to do that, and Scott Wilkinson recommends the Andrew Jones 5.1 sound bar from Pioneer. But if it's 2.1, he shouldn't get it because he won't be able to do what he wants with just "simulated" surround sound.
