These were XP66c. I don't know whether the "c" means ceramic magnets or maybe they were just the 4th iteration or tweak to the original 66. But they were better than "firewood".
I don’t think I would have kept them all those years if they were that bad. They didn't have the midrange presence of the Bozaks, nor the deep bass, and you couldn't crank them to ear-spltting levels, but they were well balanced across the spectrum and had a nice high frequency balance for cymbals and drums. Good for female vocals, too.
Like I said, I couldn't give them away. But a couple of guys at the recycling center were eyeing them. They didn't ask me if they worked, but as I was leaving, they walked over to them and were checking them out. So who knows?
Maybe they will find a new home. Either that or they were looking for firewood.
