Hello TomTuttle,

Hope you are well. Was just thinking, does that Denon 1804 have just large and small settings for the speakers, if so do you know if it sets the crossover at 100Hz like most with only small and large settings. If that is the case then you would not even benefit from a center that has response below 100, it is all going to the sub, assuming you have the center set to small.

Later,
