Thanks for the suggestions - I redid my auto setup last night on the Denon 3805 the Klipsch RB75,Rc75 abd RS35 sound awesome but not much coming out of the sub. If I crank the gain I do get boomy sound but it does not really match anything that is going on in the movie. If I leave the gain set at 1/3 to 1/2 it does make some noise but not much. I don't know if the Denon has an LFE that can be adjusted so I will check that out tonight.
I sent a note to tech support so I will wait to see if they respond.
