Home Theater is all about the surround speakers, so not sure why your interested in a center speaker?
Keep in mind you already have a phantom center speaker if you left/right speakers are positioned correctly and voices sound like they are coming from dead center.
Many people that can't use a center speaker for whatever reason (no room), just turn off the center in the HT receiver menu, this directs the movie dialog to the left/right speakers, which in turn simulates (phantom mode) the voices coming from dead center in front of you.
So basically, you already have a phantom center. But if you have a 2 channel receiver, movie watching just won't give you the same experience as a surround receiver would.
