    Some plots don’t yet have editable colours.

    Uncheck “Imp R” and you will see the IR of the filter.

    It’s there. Toggle the “Show FIR filtered loudspeaker” checkbox. When unchecked, it’s the response of the FIR filter plug IIR, gain polarity and delay.

    I looked over your system and project files.

    The export format was set for “Binary file (32 bit, int)”, not “Binary file (32 bit, float)”. This will likely cause miniDSP to see NaN when importing.

    Regarding filtering, there was an 2nd order all-pass IIR at 38 Hz and a 2nd order maximum-phase all-pass on the “FIR Phase Adjust” tab but the tab’s “Enable” was unchecked. Try removing the IIR filter and checking the “Enable” on the “FIR Phase Adjust” tab. This should give you a FIR that unwraps the LF phase for the measurement in the project.

    Can you please email info at eclipseaudio.com and attached one of the bin files (that causes NaN) with miniDSP and the FIR Designer M system and project files used create the bin file?

    What format are you exporting?
    I think miniDSP loads 32bit floating point binary files.

    Great. High delay in measurements is often the problem.

    Can you please provide a screenshot of the Import tab and Auto Phase tab?

    >> Is it correct to assume that this loudspeaker is displaying non-minimum phase behavior

    Yes.

    >> Can the phase adjustments being done around the crossover region, to flatten the phase
    >> response, be deemed to be “maximum phase” corrections seeing that we are inverting an
    >> all-pass response?

    Yes. But remember this is just one loudspeaker. Each loudspeaker is different.

    >> Is the flattening of both the magnitude (EQ boosting) and phase response around the
    >> crossover region not going to introduce audible artifacts like pre-ringing?

    Maybe. Linear-phase brick-wall crossovers also have pre-ringing but it’s rare that people say they think they can hear it.

    >> Can the same EQ concepts be readily applied in correcting the room transfer function
    >> displaying non-minimum phase characteristics at the listening/measurement position?

    Yes but I’d suggest doing a literature search on the topics of room impulse response correction and inverting room impulse responses; maybe in the Audio Engineering Society resource library.

    In the tutorial the 200 Hz High Shelf is maximum phase. Try changing it in your project from minimum to maximum phase and see what happens.
