Gumbydammit, you were amazingly accurate at guessing my age/ears. Only off by 1 year! I'm 46. Although I can still hear highs ok. I did some mods to my Fostex drivers impedance characteristics to extend the high and low ends. Worked out well. I agree the normal response is rolled off. It's a shame that more people don't mod these drivers, as really good response can be had from them, within reason, for the size/type of driver.
