If you smooth the measured responses you see that they match the x-curve quite well.

I agree with this.

A flat direct-sound response, witch gives a slightly downwards tilted in-room steady-state response, is the one that is preferred.
A speaker with anechoic flat on-axis will...

That is one way to do it - individual eq for everything, applied as you find suitable.
Not very common, I think, most calibrate their system to something closer to flat, and leaves it like that,...

Having looked at the report, I find the situation to be better than expected.

All venues follow the x-curve calibration, and deviation is far less than that shown for studios in the Genelec...

Just to clarify what I am trying to say here;



Here the term "frequency response of typical theaters" means the changes from flat caused by room acoustics.

Could not agree more, it is a great soundtrack, but still leaves you thinking how it could have been, if they just backed off 6-10dB on the level to get less compression - more impact, better dynamic...

This increases the acoustic damping in the port, reducing the output from the port and the speaker at lower frequencies, which can be perceived as "better" bass because the overall output is reduced.
