I just happened to remember, when I built my custom speakers originally, 20 years ago, I used 6 inch Vifa for the midrange, which is a good speaker, and I was told not long ago that they had improved their 6 inch driver, so I replaced the old drivers for Vifa's new drivers, and there was a tremendous improvement across the board.
Those who make their living selling drivers, have to keep improving.
Enjoy the music.
