8 is the in-room Frequency Response of the Nightingale-ii
measured with Dayton's OmniMic v2.
that the compression driver is about 2.5dB higher than the
reason for this is because the compression driver volume
is adjusted for my listening distance of 2 meters.
the microphone placed at 1 meter, it records a higher level.
I were to adjust the compression driver for a Flat Response
at 1 meter, I find the highs are too soft at 2 meters.
far as I'm concerned, a Flat Response at 1 meter is only
valid if one is listening at 1 meter away. Most of us don't.
the drivers cross at 1,800Hz, we must not forget that the
compression driver is adjusted for 2.5dB higher.
it is adjusted to the same level as the woofer, the crossover
frequency will be nearer to 2,200Hz, which is the Synergy
Active Crossover setting.
frequencies above 500Hz are similar to a Quasi-Anechoic
Response, frequencies below 500Hz are affected by room nodes.
Note the deep notch at about 150Hz. I believe that comes
from a floor bounce with the Nightingale placed at 1 meter
above the floor.
