I currently have a rc-62 for my center rb-81 for the fronts rt-10d sub and rs-52 for surrounds. This is setup in my living room. I am doing a ht room in my bonus room and its about 15 feet by22 feet. My thought was to move my equipment into that room take the rb-81s move them to the back and make it a 7.1 system. I was wanting to buy rf-7s for the fronts but my thought was they may not match the system maybee I should go with rf-82s any suggestions

QUESTION I HAVE A RC-62 ITS RATED AT 150 RMS 600PEEK AND BUYING THE NEW RF-82 II IS RATED AT 150 RMS 600 PEAK. I HAVE AN OLDER DENON RECIEVER 2807 RATED AT 110WATTS PER CHANNEL I WAS THINKING ABOUT GETTING A SEPERATE AMP AND IT IS RATED AT 200 WATTS RMS PER CHANNEL WILL THIS HURT THEM SINCE THEY ARE RATED AT 150RMS. IF IT WILL NOT DAMAGE THEM WOULD I BE ABLE TO TELL A BIG DIFFERENCE IN SOUND QUALITY AND BE WORTH BUYING THE SEPERATE AMP?
