Every speaker design is a compromise in some way. Having many drivers, each handling only a couple of octaves, can produce more linear frequency response and higher power handling, but the multiple crossovers are either going to be very expensive or will suck much of the life and dynamics out of the music. That's why 2-way mini-monitors are so engaging within their operating range.
The primary Zu driver keeps the crossovers out of the main listening frequency range. They use a whizzer cone and a phase plug to help keep frequency response and dispersion pattern more uniform over its whole operating range. For the high overtones it hands off to the supertweeter just below it.
All things being equal (which they never are), small diameter drivers generally have less cone breakup and wider dispersion than large drivers. But if the 10" cone is properly designed with a rigid material, the voice coil is big enough and the magnet is strong enough, you can get very clean linear response from a 10" cone, no problem.
Pretty much any review I've seen from any magazine is very enthusiastic about the sound of the Zu speakers and complimentary about the seamless sound and uniform dispersion of their nearly full-range 10" driver. I seriously doubt that it's a problem, and if it is, you have their 60-day return period to break 'em in, listen, and decide.
