Or is it ignored because that frequency is no longer output by the satellites? (I know it's not a brick wall)
The usual 12 dB octave high pass filters in your AVR's crossover are only about 12 dB down an octave below their corner frequency which is like 63 Hz wth a 120 Hz crossover.
If you boost overall response by 5 dB with a peaking you overcome almost half of this.
I'm thinking that you've discovered that if you boost 63 Hz to flatten the response of your system, your L & R speakers have audible distortion for peak levels.
The bottom line is that when you are out of dynamic range, you are out of dynamic range!
Lastly, what happens when you raise or lower the speaker trim levels? If for example you raise or lower the center speaker by +/-10db (example only) does that effect the bass that the sub outputs below the center speaker x-over point?
Shouldn't. Speaker trims only affect the designated speaker.
