Allow me to be envious of your newly acquired miniDSP appliance.
When you ran the miniDSP, did you run it after running other EQ programs such as Audyssey?
I ran ypao, didnt like how it sounded at the lp, so I manually adjusted the distance setting, then eq'd with the mini dsp.
oh and I ran usb cord to a cell charger and no hum, so yea I must have a noisy dc power supply.
Its amazing how much tighter and punchier the bass is now the peak is gone. When I get more time l, I am going to tweak some more, I think I can get the graph even smoother and flat out to 14-15hz. Ill add more gain in the 15hz region and adjust the Q. The Mini DSP is a awsome unit!
Here is todays efforts after I got home from work. I measured all speakers in 7ch stereo and had to do a bit of eq'ing from my previous graph. With my main speakers added into the equation I had a huge spike in the 80hz range. Yea I know my subs are running hot...for some reason I like them that way...well not this hot but yea.
