"YAMAHA ns-6490" and a simple filter.
I pulled my Yamaha 6490 speakers off the shelf. I decided to give them another listen. I'll also try replacing the stock tweeters with different tweeters to compare the sound.
I also connected a 0.33mLH coil to the woofer, limiting it at the top. Then I replaced the stock midrange capacitor with a film capacitor.
The sound has become a bit more detailed. The filter in the speakers may gradually become more complex. I'll have several episodes about these speakers.
I'm listening to the radio, recording from my smartphone - https://disk.yandex.ru/i/QsjujGN8aFM30Q
