Is it possible to use my left and right in-wall speakers in our living room as center channel speakers? I want to improve the spoken dialogue but I don't have much room around my TV to add a center channel speaker. I don't want the surround sound effect and these left/right in-wall speakers would be much closer to where we're actually seated in the room. I am using a Sony Receiver STR-DA3500ES receiver in my setup. Please let me know. Thanks.
