When Dirac Live takes speaker measurements for a calibration, does it do so utilizing the full range of all speakers in the setup, or does it utilize the crossover frequencies (if any) assigned in your receiver’s settings for each of the speakers? I keep reading conflicting information about this and am thoroughly confused as to whether or not crossover frequencies influence the filter corrections that are produced or not. The Dirac manual is of no help.

I did have one Dirac help desk person say that it is “his understanding” that Dirac always measures in full frequency regardless of whether or not your speakers are set to “large” (no crossovers) or “small” (crossover frequency specified) in the receiver, but I’m not quite understanding this. If the measurements are always done in full frequency, and you had a crossover for particular speakers at say 120Hz, seems like the resulting filter would erroneously boost the decibel levels of those speakers’ frequencies around the crossover point to match the target curve, not realizing that your subwoofer is actually handling some of the load as well.

I may simply not be understanding some foundational knowledge here. I’m new to Dirac and nicer HT setups in general and have yet to get my equipment to test everything myself. Just trying to educate myself up front as much as I can.
