Genelec 8361A Measurements and Multitone comparison with other speakers.

Thanks for more data and measurements @Nuyes 
I have a few questions:
1. Is the previous "Compression of Transfer Function H(f)" the same as your current "Compression test" graph?
2. Previous test showed from frequency from 50hz to 20khz, while current test shows only 100hz to 20khz.
It would be nice to see lower value, since we can see when to use a subwoofer or not.
Erin's Audio Corner provides compression tests down to 20hz, for example.
3. Are these graphs the same as Erin's Audio Corner's "Reponse Linearity" graphs (see below)?
4. I still have trouble finding all of your posts (here on ASR).
For example, you talk about Genelec and Kef speakers inside this thread alone.
Consider creating a spreadsheet, or main thread (like the countless ones I created) in order to aggregate/combine all of your reviews into one place.
It will make finding your reviews much easier.
Just a thought.
Love your work.

1.They are the same.
I sometimes forget to modify the title...
2.Because I measure in a room, the influence of the room is dominant below about 100Hz in the data I measure.
So to avoid this as much as possible, I limited the frequency range.
3.
My compression measurement data is similar to Erin's Response linearity data.
But there is a slight difference.
Erin seems to be using Sine sweep, but I use Multitone.
And Erin displays the compression in a positive (+) direction through separate postprocessing, but I use Klippel's module as it is, so it displays the compression in a negative (-) direction.
Therefore, Erin and my data are in opposite directions.
4.
Your idea of how to manage measurement data seems very good.
In particular, it would be good to create a separate thread and manage it separately.
I'll think about this a lot.
Thank you for enjoying my review.

Ok no takers…my guesses:
1) Genelec modified the drivers on the 8361
2) Genelec lessened the protection on the drivers on the 8361
3) The waveguide/vestigial horn is more efficient on the 8361
Did the OP measure both the 8351 and 8361 in the same setup and room? If not, perhaps that could account for the differences? perhaps this was stated somewhere in thread and I missed it

Do they have different amps/electronics? Would this cause a difference?

Is there a chance that the size of the cabinet has any effect?

As far as I understand the tests are comparable.
The larger baffle would impact directivity (which it does) but I don’t think it would have any effect on compression.
Ok I hope it’s not #2 as that would be rather low tech for Genelec.

Maybe possible to ask Genelec via email
Not clear to me that there is a significant difference? We are talking about 1/10ths of a dB. There does seem to be something a tiny bit weird going on with the 8351B above 10khz but it is still so tiny it's hard to conclude it means anything. E: The comb-filtering-like appearance on the graph makes me think it's probably tiny reflections off the mic or something.
Both speakers have shockingly impressive near perfect results even compared to other expensive actives like the Buchardt A700 or the Mesanovic that Erin reviewed recently.
This is the freakin kii3 after all

Which in your opinion is better?
I'm curious about this too if there is something in addition to SPL and bass extension that makes the 420 better.
Interpretation please I don’t understand all the graphs, please explain if you don’t mind!
