I had Polk RT-5 speakers. I just added 2 RT-25i speakers and a CS-245 as the center. I would think that the rt-5's should be the front speakers since they are a little larger. My concern is that the rt-25i speakers might sound better than the rt-5 speakers. Would it be wrong to put the rt-25i speakers in the front? Do you think they are better sounding speakers? Would this affect the volume of my home theater system? Thanks for your time!!!
