Strange routed bass behavior May 7, 2015 16:13:53 GMT -5

I am using a freshly factory reset unit with the following changes in Dirac preset
all speakers 120Hz crossover
12dB/octave sub crossover.
These changes were made so that the subwoofer response from the mains would be exactly the same as the hard-wired LFE response. This has no effect on Dirac filters.
Note that +10dB LFE is required by Dolby and dts - completely normal. I ran the same plots but with LFE 10dB lower and the subwoofer curves for LFE and Left Front (and all other speakers) overlapped exactly.
Tony - if you wouldn't mind - could you repeat your measurements with my settings and see if you still see this issue?
If not, start restoring your settings one at a time and see when the problem returns.
My source is 7.1 PCM over HDMI. Measured at XMC-1 balanced outputs. What was yours?
Please tell me if I am reading this graph correctly
Purple = full range main speaker ?
Blue = LFE
Red = LFE down 10db
Grey = rolled off bass 12db/oct
Is one of the traces either red or blue redirected bass?
