Not a bad analogy as far as analogies go, but like all the comparison isn't equivalent at more than a surface glance.

Drivers spaced a small enough fraction of a wavelength apart no longer have spherical wavefront propagation but rather couple to produce a cylindrical wavefront. You don't hear end drivers delayed...

Tensor tympani and stapedius are the names of two very tiny muscles inside your ears that attach to the tiny little bones that vibrate between your eardrum and the cochlea. When these muscles tense...

A crossover might be used between center driver and surrounding ring to make a sort of virtual concentric/coaxial driver.

Or, subgroups of drivers can have shaded level and phase to make a steered...
