I was just looking at the DSP specs and was wondering...

What does the EQ in 9a currently have as the Q on each band in 4-channel mode vs 2-channel mode? And did this change since 8c? I know there was a brief problem with setting the bands properly between 9 and 9a.

The reason I ask is because I'm not sure of the results I'm getting when I adjust my 4-channel EQ to remove the bass from my front speakers. It seems that even when I crank down the low frequencies on the front speakers, some bass is still getting through. Am I getting frequencies that are "leaking" out from between the bands because of incorrect "Q" values, or is it something else I don't understand?

In a related question:

How exactly is the Loudness feature implemented? Since it's implemented in the DSP software, there's no description of it in the spec sheet. Is it a modification of the EQ parameters?
