Ichigo_Kurosaki,

The most likely problem you are having with your subwoofer is in the settings themselves which is causing the sub to receive not enough voltage from the subwoofer pre-out for proper output. That is noted by the -12 setting. It is highly likely this is the problem EVEN with the gain set to max on the subwoofer. Use the knob on the Ep350 and set it a little past half way and change your settings from -12 to +2 for the sub on your receiver and see if that makes any notable difference. If it does then we found the problem and we can tweak your system for proper calibration from there.
