What high efficiency speakers are people using other than Klipsch, Zu, Omega?

After owning standard box speakers for most of my life, several years ago, I switched to open baffle - Caintuck Betsy’s (recently Alnico)  They need supplemental bass (unless you do as Steve - see the Big Betsy thread) but I absolutely love the sound.

And it sounds like the new F15 Baffle that Caintuck is offering is another good option.
