Can't speak directly to what you are experiencing sinse I am not there to hear it, however, good quality Low Frequency reproduction, free from distortion, is much more subtle.
What most people hear as "loud" in Bass is actually distortion.
That said, what is your AVR?
I would always recommend using the AVR room correction first with the Subwoofer settings neutral. Unless you are on 10 year old Audyssey or YPAO or something like that...
