Do you have the response curves after calibration?
Yes, it looks like Dirac reduces and smoothes out the "Measured" by about 10dB.
The resulting target curve looks quite smooth but it's just lacking of bass when playing at master volume between -45db to -55dB. Surprisingly, after more testing, when I increased master volume to above -40dB, then the bass sounds really nice and well integrated with the main speakers.
To solve lack of bass playing at low volume, I click on every "dots" on the target curve and push it up by 3dB. This completely solves my lack of bass when playing master volume between -45dB and -55dB. Here is the new curve after adjustment. I don't know if this affects the integration or not. Is this a good idea?
Looking at the main speakers Target Curve, I have 2 different concerns:
1. Why is the dip happening so close to 100Hz? I set my crossover to 140Hz, but it seems the "cut-off" for Main Channels is happening around 110Hz.
a) Is this a good sign or something else going on?
b) I thought Dirac Live will tell M10 V2 / BluOS what the best crossover point is, but it didn't change the one I set. Should I set crossover to something like 100-120Hz to reduce localization of the bass?
2. Above 10 kHz, I don't know whether it's the NAD M10 V2 amp or what is causing in this big dive. My Polk Audio TL3 speakers are capable from 90 Hz to 28 kHz @ -3 dB, so it shouldn't have this kind of big dive between 10-20 kHz, which is causing some missing clarity on the high end. Would Dirac Live full version correct this?
