Quote:Generally speaking, it is not possible to use an alternative measurement system to measure your room and produce a frequency response that matches the calculated response in ARC. Bear in mind that the response shown in ARC is an average/mix of the 5 mic position measurements, whereas a response from something like REW represents a measurement from a single mic location.
That being said, I was able to discern a notable difference in the measured response with ARC on vs off. In Movie mode, with all speakers crossed over to my sub at 60Hz, I was pretty happy with the ARC on result.
In Music mode, with my Front speakers running full range and no sub, I was a bit disappointed with the resulting bass response with ARC on. ARC did a good job on correcting the room mode issues, but I felt that the bass level was unnecessarily attenuated, which surprised me since this wasn't the case when the sub was involved. As a result, I've added +4 to the Bass setting for the one input that uses Music mode and 2.0 source.
I'll post some graphs from REW, but I need to redo some measurements first.
