Probable dumb question - Where's the midrange driver?


It seems all the "audiophile" speakers I have seen contain a midrange driver (5 - 6.5"). Looking at the 3 pi's and 4 pi's I am wondering how they can use a large woofer (12 - 15") without a smaller midrange driver.

Please note I'm asking out of sheer ignorance - I'm not trying to kick up any dust.
