I have an SVS 20-39 PC+ and with the gain on the sub approximately 1/3 of the way up, the setting on the receiver at -2 (rcvr goes to +10) and the auto on switch on AUTO, I have bass regardless of the volume level.

It is right in a walkway to my bedroom and so I usually put a hand on it as I pass by just to feel it work...even when the volume is very low, it is still is doing its job...supplying impressive bass.
