How important is it for all of your speakers to match? Is it okay if your rear speakers don't match the fronts and center? Also, I am needing to replace my current fronts and center. My budget is $250. Any recommendations? I have looked at the NS-P1II Northridge Series 5-Piece Home Cinema System but the N-centerII looks pretty big. My TV is only 24 inch right now. Would it be okay to sit something this big on top of it?
