Can you find/get the voltage drive? I would be very grateful. I only have the italian magazine one.

After some more listening tonight, I think I prefer how my fully active setup sounded.
I will probably make another go at trying to improve those dsp settings.
At a first glance, looking at the voltage drive for the K2S9900 posted at this site, the curve looks pretty "simple" to translate into dsp-settings. But then I realise it is dbV on the y-axle and not Db. Are those equivalents? Or do I have to convert dbV to Db in some way to know what to enter into the dsp?
Can I use S9900 voltage drive for my speaker you think? The compression driver is the same, but maybe not the horn?

I note that S9900 has this shelfing in the bass that I also added to my own settings.
I think your best option is to push 1audiohack to do the measurements and crossover settings on his, and share them on the forum :D
What measurement tools do you have at hand?
OK, I just reread your first post.
If you could take precise measurements and share the impulses then we could probably be able to try some crossover settings.
I tried to change to Linkwitz-Riley 24Db/oct and, whoooah, the sound I want!
I must measure to see what happened, I guess the cancellations/suckouts after the crossover point dissapeared.
Active LF, Passive HF/UHF settings:
24Db/oct Linkwitz-Riley slope at 600Hz.
+8Db low-shelf at 136Hz, 6db/oct slope.
LF delay 0.10m.
It sounds insaneley good now :)
If I only could replicate this sound fully active, with that extra percentage clarity and dynamics, then I would be in heaven.
Who will convert the 4365 HF voltage drive into dsp-settings for me?! I promise to send some Swedish delicacies to you! (we have some scary stuff as well, fermented herrings, snus, cray fish etc)
From a city-billy audiophile..
I found the 1501Fe to sound best for me in a 2 - way with 2445/Be/500hz Edgarhorn when crossed over @ 375hz 24db LR and the Horn @ 750Hz 18db oct BW and passive EQ (Pi spkr X-over type).
I'm looking at 2206/E-145/2226 passive 2-way run with tubed amp bi-amped between 100hz to 150hz with SS amp on 1501Fe for LF duty.
All the cabs can be small and still provide all the LF reproduction I need,
Just my 2 cents...

That is the voltage drive G.T. recommended for bi-amp operation. A person plugs that voltage drive into their active/DSP filter. For example, a Crown can emulate that. Those two voltage drives are an invalid comparison. I wish I could find the thread all that information was posted in.
