IMHO,since you do not have a LP filter in place for the full ranger,at frequencies above 8kHz(and upto the rolloff point of the full ranger),the amp would see a load of both the drivers in parallel ie ~2.7 ohms.
That was my exact point. I was reading about frequency ranges of various musical instruments and voice. It seems that most of the musical data is between 80Hz to 7Khz. I agree that above 8Khz, it will be 2.7 ohm but below 7kHz , it should be much higher.
