Ah, I see. I suppose you could go adjust up the gains in the DSP (or at the amp) after Diract. I know you already know this , and it's obviously not desirable.The individual drivers post Dirac measurements did match the Dirac targets very closely but the relative levels between them did not match the relative levels between the targets set in the filter design screen. It set the sub level (as viewed in the Dirac tab in the plug in) to -12db or so... Which killed the sub level and messed up the xover point / phase relationship between it and the midbass.
I've noticed that the Dirac tab in the MiniDSP software shows what gains it introduced on each channel, and those can't be modified. It's pretty annoying because, even if you turn Dirac off, those gains are still in effect, which seems odd to me. It's documented in the manual that way as well (I.e. the expectation is that Dirac gain adjustments are in effect irrespective of whether you have Dirac on).
That actually forced me to start a tune over again once, once I realized it was doing that.
