The rising response above 1kHz is due to cone breakup, which is attenuated by the midhorn, it's front chamber and other features. As a direct radiator, you'll have rising response as shown in the measurements. One option you might look at when using the Delta 10 as a direct radiator is to attenuate this range with an electrical filter.
