I present the following data to support the single-point predicted response hypothesis, and hopefully to convince
that expecting Dirac to conduct post-calibration measurements is really not necessary.
- Single-point Dirac calibration with mic in the MLP.
- Bass management turned off in the MiniDSP 88A, all speakers full-range
- REW measurements presented in 1/12 smoothing (closest match to DLCT smoothing, AFAICT), except for the LFE, which is unsmoothed. Mic is not moved from the position from which the Dirac measurements were made.
- The LPF for LFE in the AVR was untouched (120Hz), which is why the REW LFE measurements show roll-off above 120Hz. Dirac does not see the LPF.
I am presenting only the left channel and the LFE measurements. I have the right and center measurements as well, but this post was already getting pretty long. How about that LFE measurement with Dirac correction?
