Hi All, I have a question regarding the sound levels on my BA system and Yamaha rx-v450. I have all of the speakers set to small, the bass out to my subwoofer. My question is what level should I have the crossover freq at. It's at 80hz right now. I just want to make sure I'm getting the optimal power flowing through the speakers, but do not want to overload them. Do these specs seem right? Thanks.
