I currently have just a setup across the front of my room. All three speakers are Infinity Primus series, with a center and 2 front surrounds. I found a great deal locally on a set of Polk Rt1000 flloor standing speakers that have a subwoofer built into each. My question is, if I keep the Infinity Primus center channel, and then move the Infinity bookshelf speakers to the rear, and use the Polk speakers in the front, will that affect the sound quality any because they are not matched speakers?
