Let's take a look at conventional approach to waveguide design vs QSC's Directivity Matched Transition (DMT), and how it applies to a typical performance venue.
Clip 7 of 9 in QSC's House of K - Installed Sound Video Series
@MrVic1954 The demonstration in this video is basically explaining that every woofer has its own coverage characteristics, and a typical 90 degree (45 degrees off axis) high frequency waveguide does not necessarily suit every woofer size. QSC carefully matches the waveguide coverage to each woofer size as shown, called Directivity Matched Transition (DMT).

Maybe I am missing something. Is the key here the 45 degree spread no matter what size the speaker? Or is there more to it? Thanks
