i believe i read here a long time ago that matching the fronts is key. now before i continue i will tell you what i have, i own the Polk audio RTI10's and the matching center (but lower model), now what i find is that when i go into futureshop (im limited to buying there, it sucks), but anyways, i go into there theater room, and i find the $699 or around there energy center channel is just soo amazing. maybe its the room, maybe its both, but it def. makes me want to buy that center. but i just bought these fronts last year so i dont really want to change them out. so my question is, can you match fronts and center? or would it just sound not right from having 2 different brands up front? thanks
