i would like to keep it under $1000, room size is 20'x25' with vaulted ceilings, and cermic tile flooring. I am thinking of buying a 7.2 reciever but will be running a 5.1 setup, therefore I will use the exising two channels to "biamp" the RF-7s. I am also looking for a second RT-12D to match the other. OH, and thanks for the warm welcome!!!!!![]
