That there were no good older 2 way designs.They were challenged by power handling or bandwidth issues that led to compromises.
The KEF crossed its 8" woofer over at 3 kHz. That's a wavelength of 4.5 inches - which means that its directivity nearing the crossover point would be exceptionally narrow transitioning to a dome tweeter that immediately changes the situation to that of wide dispersion. That's the kind of inconsistency that severely impacts coherency.
edit: One of the nice things about the Advent is its driver blending. While it had a 10" woofer (nominal 9" piston), it crossed over to tweeter at 1 kHz for the original and 1.5 kHz for the New Advent. Even at the higher frequency, that is right at a 9" wavelength. In this case, the tradeoff was at the expense of top end response due to the large tweeter. But its sins were largely that of omission, not that of an audible driver transition.
