Hey i am a new person to the audio scene so please bear with me. I am sure i will have many dumb questions, but hopefully all of you can help me. I have a very large room that we just built and i am trying to make it into a home theater. The room is about 850 square feet with 13 foot vaulted ceilings. I was thinking about buying the Klipsch RS-3II speakers for my rear surrounds, the RC-3II center channel, and the RF-3II speakers for my main. I was also thinking about getting the KSW-15 subwoofer. I am looking at either a Yamaha RX-v1300 or a Denon AVR-1803 reciever. Do you think this set-up will have enough power for that large of a room, or will it sound bad? I am not really a big time music lover, so i am just getting this system for movies, video games and maybe a little bit of music. Thanks for your help!
