Thanks for reporting back with your listening tests.
The results indicate that the crossover and attenuator components need to be designed to work together in synergy in order to provide the desired response.
Have fun experimenting. I'm interested in finding out where you end up!

Exactly. On the right channel (L-Pad side) changing the cap and coil to at around 3.9uF + 0.44mH sounds very similar like the left channel (series single resistor) where the values are 4.7uF+0.26mH.
The sound it is a matter of taste I think. With the single resistor it is calmer, smoother top end and warmer the speaker globally. The L-Pad version with the new values also very good. It is natural sounding, probably has a bit more dynamic and extended frequency response of course. The upper treble is stronger. Both are very good I think, difficult to decide. They have different tonality for sure. I will listen the L-Pad version for a while.

I give the edge to the L-pad version because this is the natural and original characteristics of the tweeter. In the end it was worth to try 🙂
In summary, the L pad method of attenuation in conjunction with a change in crossover component values gives you the greater listening pleasure.
Sounds good to me! 👍

Yes, the L-pad version is the latest. I like it.
We forgot to examine the 3rd option...
What happens if the single series resistor is between the high-pass?
I mean first the series cap, after the series single resistor and lastly the parallel coil. Probably the sound would be similar to where the single series resistor is before the high-pass? This is another story...

Which has a happy ending! 😎
The single series resistor may be placed before or after the capacitor to equal effect.
(Just don't place it after the inductor.)
I think Allen means that there are instances when you may wish to increase the impedance of the tweeter to match that of the other drivers in the speaker system.
Doing so requires calculation of the crossover components to match the increased impedance.

Not at all, Galu. I don't understand why you think it's not good... karoly's results speak for themselves, but in a controlled environment all three methods can achieve the same result.
I don't think it's not good - just that each method has to be individually calculated for.
Surely that's the point we've been making all along?

I meant, if placed after the inductor, different L/C values would be required.
Better if I hadn't added that, as it wasn't pertinent to the question asked.
It's ok, we're just chatting now.
If that was the point then I'd have been pushing for a simulation. As far as I have been concerned it has been all about chance.
Are you familiar with the British idiom "A chance would be a fine thing"?

Lol. Each iteration is a chance, with a bonus of increased knowledge of the situation.

SPOCK: Difficult to be precise, Captain. I should say approximately 7,824.7 to 1.
KIRK: Difficult to be precise? 7,824 to 1?
SPOCK: 7,824.7 to 1.
KIRK: That's a pretty close approximation.
SPOCK: I endeavour to be accurate.

IIRC the second is from 'The Ultimate Computer' which reminds me I could go for a Finnegal's Folly right now 😉
Just one more quesrion. How influence the tweeter's sound that at the L-pad I slightly lift up the values either series or the parallel resistor? Let's say calculator shows 2.7/15ohm but I create 3ohm/15ohm or 2.7/18ohm. Both are around 8.2ohm impedance but which has advantage or benefit?
