OK. I guess you didn't know that the Klipsch reference series has a reputation for being fatiguing for music and movies. That's why they are a love 'em or hate 'em kind of speakers. Very common for people to eventually upgrade from them to something else even with HT usage because of that. Although they tend to sell very well in brick and mortar stores because the extra treble energy makes them initially sound better than other speakers.
Of course they do have a reputation as HT speakers. But that's because they have a reputation for high sensitivity which allows them to reach higher volumes, even though their specifications have been shown to be inaccurate through third party testing.
But you should probably like the Klipsch because the horn is a wave guide design. As you said, that's what's important for good speakers for music, right
