Let me ask a question about the crossover settings for the receiver. When I have the main speakers set to SMALL and their crossover at 80Hz. I'm expecting nothing to be sent to the mains much below 80Hz. I understand there is a gradual rolloff. Is this the correct assumption?
When I ran the LF/sub and RF/sub low frequency sweeps on AVIA with the described setting I was noticing a serious amount of air flow coming from the ports of the M60s in the 40 - 60Hz range. Does this means the internal crossover in the receiver is not working propery?
