Not Emotiva, but I recently explored Dirac live on Bryston's SP4 with a battery of measurements of how the system works in our living room. (If anyone has recommendations for
acoustic measurements that could help illuminate some aspect of AVR or SSP performance to add to the battery in that review, I'm all ears. Acoustic because I'm not going to buy an Audio Precision. Electronics just aren't my interest, except room correction)

The SP4's bass management is the best I have seen on an AVR or SSP. Dirac corrects to whatever endpoints the user selects with the curtains. The automatic target curves correctly imply that correction should be broad: up to 500Hz for the sub for example. The crossover is the user's responsibility, but the processor gives a skilled calibrator all the tools she needs: adjustable slope, delays, separate filters for each channel, etc.
The challenge is, getting a really good satellite-subwoofer blend places steep requirements on the speakers and subwoofers. The main speakers need smooth response down about an octave below the crossover,
and the subwoofers to have smooth, clean, resonance-free response an octave above the crossover!
