I will re-measure these in 1 session with the same technique to be sure (that null at 150Hz is suspiciously different), but look at the difference between room correction products: Audyssey XT32 (with subs) and AcourateDRC (without subs).
Audyssey was configured with Dynamic EQ, Midrange Compensation, etc. turned off.
These are corrected measurements of my Revel F206s in the media room. This time, they are presented with the same smoothing and scale.
[EDIT]
The measurements methods were different, and the measurements were performed about a month apart.
The Audyssey measurements were taken with my laptop plugged into my 4700 receiver via the front HDMI port using the MMM around the MLP with pink noise from REW with ~90 averages each.
Signal path: Laptop -> AVR-4700H -> Peachtree Nova 150 -> F206 pair
The Acourate measurements were taken with my Blu-Ray player streaming a 20s unfiltered pink noise WAV file (downloaded from Dynaudio's web site) through the OpenDRC-DI. The mic was stationary in the MLP, and each measurement included 28 averages.
Signal path: Sony BRD -> OpenDRC-DI -> Peachtree Nova 150 -> F206 pair
There are obviously enough disparities in the measurement methods to cause some differences. But, I think the data are still relevant and interesting, as long as the above information is known and considered.
