Here's a REW measurement with 1/6th octave smoothing. This is using the CD analog input.
Edit: forgot to mention this is with DefTech BP30 speakers
The first one is none vs flat:
Blue line is no EQ and green line is flat EQ. I do see some correction, but not "total" correction
This next graph is No EQ vs EQ flat vs EQ audiophile1:
The third purple line is the audiophile EQ. Notice that below 200 Hz the line is close to the EQ-flat line (green), but above 200 Hz it follows the no EQ line (blue)
Next graph is no EQ vs EQ flat vs EQ natural:
The purple line (EQ natural) has a boost of 3 to 4db below 200 Hz over the EQ flat line (green) and a cut of 1-3 db above 10 KHz.
Overall, I'd say it's working as designed. However the room modes are not totally corrected by the EQ. I guess this is not surprising, as it's difficult to do that. My next step is to probably get multiple subs (I have none now) to tame the room modes.
Curt, do these measurements seem in line with what Trinnov (in R-972) is expected to do?Edited by amt - 12/2/12 at 9:32am
