Yes, for 3 I meant; Impulse B-H7In "3." did you mean "impulse tukey" or "impulse B-H7"?
It is interesting and educational to confirm the anechoic SPL response of a DIY design. Since you are relying on Dirac to perform the EQ there is no need be concerned with the that response however. I would expect Dirac will end up with a similar LP response no matter the initial anechoic response. Speaker and LP placement in the room along with other room acoustic characteristics will have a much bigger impact on the sound quality than any reasonable difference in a speakers anechoic response.In practical terms, does the "B-H7" window function analysis show that no further EQ for the dipole peak is necessary? Or I'm misinterpreting something? In fact my in-room measurements (multispot listening window averages) show that the 300Hz peak is attenuated by the two dipole speakers+room behaviour to within +/- 3dB of the house curve. And that's even before applying Dirac, my preferred DRC. Obviously I am looking for a justification to leave it like that :wink2:
