Single driver horns freq response
 

Dear All, I would appreciate to learn when single driver speakers based on Horns (Jordan driver Jx92S) still have as a target to sound flat 20-20Khz into a room.
Or their high presence/physical sound is not due to the horn/design but simply to a non linear frequency response ?

I am looking this info to determine if a digital equalization of the room for a flat sound will be beneficial also for this type of speakers. (speaker will be measured into the room and then correction will be done)

Many thanks
