Partial correction and target as EQ

[Dali_20]

Hello everyone,
I cannot understand what the "Use Target as EQ" option should do in partial correction mode.
Whether it is activated or deactivated, the corrected response curve has the shape of the original measurement beyond the correction threshold.
Also, the correction filter always looks as a straight and tilted line beyond that threshold.
Am I missing something or is it a bug?

Try a partial from e.g. 1 kHz and do something with the target above … and post a chart here … and we’ll see.

The target clearly works as an eq above 1kHz here. See how the correction traces the target above 1kHz.

Ok, then that's what that option does. I thought it would create an inverse with IIR or something like that.
I got it.

I see that there is the possibility of disabling TTD but not room correction.
Is there a way to align IR and phase only of the drivers at sweet spot without applying room correction?

I would like to experiment a little with other correction systems that work on large area (MSO/ Dirac ART) but I cannot find a way to get only digital crossover/alignment of drivers on Audiolense.

Maybe trivially putting the window to 0 or limiting correction to 10hz, leaving TTD full range?

I know it's a bit unconventional use case...

Partial correction, frequency correction only to 1 Hz will do this.

 

[Dali_20]

Partial correction, frequency correction only to 1 Hz will do this.

But without the frequency correction is the sum on the crossover correct?

The sum of the crossover is correct, but the sum of crossover plus speaker is what it is.
