With regards to your capacitor leads there is No antenna effect of concern in this part of the circuit, all the speaker cables alone is a large antenna and is not a problem for a competently designed amplifier, so don't get paranoid and start twisting and bending component leads, they only become more fragile of such abuse and will break easier.
Thanks for support!
I directed the legs of the capacitors upward only because there is a lot of space inside the spheres in terms of volume, but there is not enough space in length. And in this state, I just put this bunch of capacitors on the bottom for now, I made the cable as short as possible, but so that it was comfortable to put these cables on the terminals and on the tweeters.
And you're right, my goal for now is just to hear how they sound. But in the future, I want to make a separate box and make a frequency switch. At 6.5 kHz (as it is written in the tweeter's passport), at 10 kHz (as it is now), at 14.5 kHz (I have a slight drop at this frequency when measuring Diatone) and at 16.5 kHz (at this frequency there is a decrease in measurements). To be able to experiment with sound.
But I plan to produce this separate box with a crossover in the distant future (maybe in a month). Now I want to enjoy the sound. Surprisingly, the detail increased by 20 percent, I began to hear more nuances.
In addition, when connecting these tweeters to my acoustics, another problem was revealed: I have a very thick cable from the amplifier to the speakers, and even having bought a thin cable from the speakers to the tweeters, I could not fix them well enough in the terminals of my Diatone. I don't want to change the terminals on the Diatone speaker system. This is a complex process and will destroy the authenticity of my speakers. Therefore, I will invent a special adapter made of pure copper (or pure silver, if it is not very expensive).
I do not think that my new invention (this adapter or splitter) will be of interest to anyone. It will clearly screw (?) only in my Diatone.
