I briefly had the JBL Sovereigns S7R (I think). The ones with the JBL 375 compression horns and 075 bullet tweeters. They were the only speakers I’ve owned that seemed to sound good with most any electronics.
I also briefly had the Metregon stereo speaker but didn’t care for it. After I sold it I was told that you had to raise the front of the speaker (in relation to the rear feet) to get the best sound.
