I have a quality sub cable going to the subwoofer from my Onkyo TX-NR808. I believe it is set at 20Hz frequency response? That is what the Audyssey mic calibration set it to. It would probably be at about 76% volume when it happens and I always frown and turn it down right away.
Sounds like the volume on your sub is set too high, I'd scale it back to no more than 50%, maybe even 33%. Are you using the LFE line input on the sub? You should in any case. While the LFE input usually bypasses the sub's crossover setting, just to be sure turn the sub's crossover setting to max.
Not sure what you mean it's set at 20hz, do you mean you have your speakers crossed over at 20? Or the LPF of your LFE? I'd use 80 or 100 hz for speaker crossover in most cases (what are your mains?), and 120 for the LPF of the LFE channel.
