I totally agree on everything! And the photos of the crossover you posted for the brave people are nectar and ambrosia for me! I think a well built XOver even if I could not see the RC network with the 8 ohm resistor and the 2.2 uF cap. Unfortunately I do not have the parameters of Thiele and Small of the MA TS025 tweeter, but I had fun simulating on BassBox Pro what happens to the frequency response applying the same RC network (with same XOver to 12 dB / OCT) for one of the tweeters I know a lot good (CIARE HT262). Just for fun I posted the calculated graph where we see that, in the case of HT262, the effect of the RC (yellow) network would be very similar to that of a 2.7 ohm external resistor in series (red). The thing has very intrigued me and since I have a pair of L_PAD not yet used I will have fun experimenting (without opening anything) the effect on the sound of my RX6. Of course I will never compare it with your original RC network, certainly much more serious than mine (not at all rigorous) "simulations"!
