Perfect coupling tales place when either of two circumstances are present: the driver center to center is no more than 1 wavelength at the highest radiated frequency or the radiating area comprises at least 80% of the vertical plane. But practically speaking a wavelength to wavelength between radiating planes is usually adequate; integration may not take place until a wavelength or so from the radiating plane, but unless you're listening to it that close it matters little. Even when the radiating plane to radiating plane distance is over a wavelength integration takes place at some point.Because of driver frame widths perfect integration at 10 kHz, for example, is difficult with a 1.3 inch wavelength, but even if integration takes place 10 wavelengths from the radiating plane that's still only 13 inches.
