I just bought for myself a Sony stereo DH800 and my present speakers are Infinity Minuette that I have since 2009. My objective is to have a home theatre with a very clear voice from the centre channel. I would like to have like a recommendation for replacement speakers or just replace the center speaker. My room is 12X14 with two free-standing walls that do not go up to the vaulted ceiling and two walls that do go up to the ceiling. My budget is flexible but nothing above the capability of the receiver. Please help me out with it.
