You're going to have to tell us how you have them hooked up, since they provide several options of full speaker level, or combination of line level/speaker level.

Since the internal crossover in the subs is non-defeatable, you would not be able to use your crossover in your receiver for your mains and its associated subwoofer out signal, so you would definitely require the mains be set to large.

Then you have the option of sending full range speaker level to the speakers and feed the subs from there at speaker level.

Alternately, you could feed speaker level to the speakers and feed the subs separately from full range line level through a splitter at the receiver.

Depending on which of the last two methods you have chosen determines how you set the level.
