Actually one can argue that ALL boxes have diffraction.

It's just a matter of which frequency the transition from 4pi to 2pi radiation take place.

So just because the design is such that time domain and frequency response problems are minimized or eliminated does not mean that the box no longer diffracts.

The bigger the front baffle, the less sound energy in total are being diffracted and the lower the frequency when full diffraction happens.
