Horn speakers especially high frequency horns can sound sharp or brightr or screechy or whatever but properly done will do trhings that the ubiquitous dome tweeter simply can't. Mounted on a waveguide and using severe toe-in provides a very wide sweet spot, about as wide as the speakers are apart. Also the wavegude when positined as mentioned prevents or limits the damage strong early reflections cause. Hard to go back to domes after hearing a good horn/waveguide setup.
Pink Floyd never played through dome tweeters! 😈
