With my Yamaha 5740 receiver, I have the option in the Manual Setup menu of directing my LFE frequencies to either the sub, fronts, or both. The only time the sub outputs is when I select "Both". I'd rather use the SWFR setting, but I hear nothing when I select that output. The sub crossover is set to 60Hz at the receiver and the sub's amp (90Hz setting made no difference), the volume at the sub is at 7 (for what that number's worth) and the phase is set to normal on both also. In "test" mode, I do get white noise when I select the sub, and obviously I have the sub "level" at the receiver set to an audible level. Am I missing a setting somewhere?

Thanks
