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.
I have Dirac Live on both my Pioneer LX505 receiver and my MiniDSP SHD. On the Pioneer, it ignores any speaker settings because it uses the Dirac measurements to automatically set them as part of the calibration, though you can change them afterwards. On the MiniDSP, the measurements are inclusive of crossover and EQ, as u/not2rad noted. YMMV.
