I have produced a graph but it looks like I need some help. Thank you.
Marantz 8801. Aux input right channel on front.
KK DXD 8801. XLR
Mackie 626 Active fronts. XLR
Audyssey both off and on.
Crossovers at 60, Audyssey and 80 manual.
Asus A6m Vista 32 laptop.
New Galaxy CM140...
I calibrated both sound card UCA202 and SPLmeter/mic (Galaxy CM140), set the levels and then run my first room measurement.
The result is a disaster: a terrible "yoyo" in the freq. response, and similar shape for the waterfall.
Here is the graph: LINK
Any suggestion, comment, support is...
