Part of my "reference rig" includes an Epifani 3X10. I have the tweeter set a 12:00 when customers demo basses through it, but when I use it live, I tend to turn the tweeter off and boost the highs on the preamp just a bit to compensate. I've found that the 10s translate the high-end well, but I can tone down that "high-end zing" that isn't always needed all the time and in all playing circumstances. I think the next cab(s) I buy will probably be without tweeters.
