Hello all, I am a newbie here and I am setting up a new home theather in which I've used the SC-50 (in ceiling x 4) for my surround and back surround. I would like to get some advice on which speakers should I purchase for the front/center speakers, as well as the subwoofer.

Additionally, I would like to receive some guidance on which receiver should I purchase, as I'm replacing my old 5.1 receiver by a new 7.1 one.

As the SC-50 are 100W each (8 ohms), can I purchase a receiver with, for instance, 110W or 120W per channel , as long as it's 8 ohms?
