Hi I have recently upgraded from a 500w rms Logitech 5.1 sound system to a home theater system which is a Onkyo 609 receiver, 7 yamaha HT series speakers and a yamaha YST-SW216 sub, with my old system i didn't have all the options i do with this new setup, i have basically tried to set it up so i cant blow the speakers when listening music via hdmi from my laptop at parties, the issue was having is that some songs i can play at 85 with no distortion where as others the woofers in the towers start popping at 70 yet the high frequency audio is still quiet, these are the settings i am using at the moment to solve this problem(cross over frequencies - 80hz for towers 100hz for center and 120hz for 4 small speakers) (sound levels - 0db for towers and center and -3 for 4 small speakers) ( lpf crossover is 120hz and sub is set to -10) i have also set max volume to 85, turned on music optimizer, turned on dynamic eq and turned on dynamic sound level to medium which seems to solve the popping woofers, with these settings it seem that every song i play does not distort, can someone confirm if the settings i am using are all right or am i trying to get too much sound out the system, my main experience is with car sound systems where you don't have to worry about harmonics of a room and can set the gain on the amps so they never over power the speakers. thanks
