- The speaker itself works well.
- Tweeters are just a dummy, I removed the tweeters purely by chance, as chips got into the diffuser when I adjusted it to fit the seat. They are removed and put back on, while there is no difference what they are, what they are not. Without them, the sound is even better, but this is due to the fact that they no longer cover the main speaker. But it doesn't look good without them. I even tried the wires in the tweeter, which are wound into a coil, connected through a capacitor to the radio, but they rustle almost inaudibly and there will be zero effect from them.
