I recently bought DSP and ran into a little issue. Hoping that someone here might help me out. My receiver uses Audyssey. I had a fairly flat response to begin with but audyssey messed it up a little bit. Anyway, the issue is that as soon as I include miniDSP even without any calibration, it brings the graph down a bit starting from crossover point. Why is it doing that even when all the settings in Dsp are at default? This introduces a dip from crossover point to higher frequency (100hz). I am trying to get a diff of 10db from 30 to 80hz (Hardknee curve. Please google if you are not familiar with it. Its a better version of house curve). Following are the graphs.
1 - Original
2 - Audyssey Vs DSP (no equalization applied)
