When you have the sub set at 75 db, what is the actual LFE channel in the receiver set at? I know with my SVS they stated to try not to have it below 1/4 of the range (mine for example goes from -12 to +12, so don't have it below -6) because sometimes this will not allow the sub to be triggered out of sleep mode. They say it is better to turn the sub itself down a touch and move the LFE level in the receiver to a more neutral position.
Worth a shot if you are in the lower end of the range.
I think it was set at -2. Would it be worth starting over with a new soundmeter calibration?
