..I design speakers.
I couldn't find any measurement for that speaker, or indeed - most Klipsch speakers.
-with that in mind, IF the crossover is steep enough at 2 kHz to mitigate the upper freq. "break-up" of the 10", and IF the dispersion of the horn is well matched to the dispersion of the 10" at 2 kHz, then it should be good.
IF it's not, then:
1. you could have some narrow-band peak/"spike" ON-AXIS (0-degree axis or "aimed straight ahead") and only slightly off-axis with respect to "break-up" (uncontroled cone motion that leads to a spike or grouping of spike's in the frequency response).
2. the off-axis response could be poor off-axis with an apparent depresion/"dip" in the freq. response somewhere beyond 15 degrees +/- (from on-axis). This would be around 2 kHz (particularly 1.4 to 2.5 kHz).
Regardless, it's going to be a more directive (narrow beamwidth of sound as freq.s increase) speaker: This typically results in a more forward sound with less ambiance, though sometimes better imaging. Klipsch is also often a bit more efficient than other manufacturers - which usually results in a more dynamic sound while have less low frequency extension for the loudspeaker-box's total volume.
