The average human ear in its prime is only suppose to be able to hear up to 20khz, so what is the point to go above that?
I don't know if this is the answer or not, but maybe inherently, speaker design makes it easier to obtain the higher frequencies easier and more economically. Maybe with amplifies it takes a harder and takes more money to do it, so when you factor in the human ears limit, there really is no point dumping more work and money into going above what it can hear.
“An engineer explained to us that hundreds of ear impressions were gathered in the name of research, and while each one obviously boasted its own unique shape and size, one single characteristic remained uniform across the board: the entrance into the ear canal is not a perfect circle, it's an oval.”
