My ears are 31, and I get by fine without tweeters. When you look at the graph, keep in mind that what you see at 10K and 3.5K are humps/resonances in the response (that I think are less audible a little off axis). Compare 15K more to 6-7K (as a baseline), and you'll realize that extend fairly high. I think you actually get more extension than some big popular soft domes.

IME, most fullranger folks that use high frequency help do so as much to broaden the dispersion up high as to extend the absolute response (when it comes down to it, not a great deal happens above 15Khz). "Add some sparkle" if you will. Many also seem to enjoy the "phase-y" sound you get when a super tweeter is spaced well away from the fullrange driver. I don't dislike the addition of super tweeters, but I am perfectly happy without them. If you decide you need them, there are fairly inexpensive options.

Now, what enclosure are you thinking of? You know that the box needs to be perfectly tailored to the driver, and computer simulation has allowed "t-line" design to progress considerably in the last few years. I attached a pic of and link (sorry, its another forum, but it is the only place I have it posted) to a t-line/tqwt sort of thing for the BetsyK. I'd be happy to talk more ideal boxes and the need for tweeters anytime you want.
