If the speaker calibration is done with an SPL, and/or a calibration disc like Digital Video Essentials, and provided all speakers are correctly set at the same level, what is the need to adjust the center speaker volume in Trifield? Shouldn't it be already calibrated to sound at the same level as the L/R channels?

I understand the need to tweak depth, width and so on, but center channel volume? Please explain.

Also:

>(I set the EQ at full range, which prevents the "dull", rolled off sound that some people hear).<

What is the EQ full range setting for, and how it affetcs the sound? I know it goes from Flat to EQ1-3, but that's it.

And on that note, anybody know what the Rear LPF setting differences; spome of these changes are so subtle, they are difficult to pinpoint.
