@soliloqueen @abbey road d enfer ,
I am not even sure if i agree or disagree on this, or if we are even talking about the same thing.
Here's an example of a typical k67 behaviour. This is the response of cardioid vs omni. Both are campensated so that cardioid seems flat, just for the effect to be more obvious. Both sides are just summed together at same level. Green is cardioid, blue is omni. More than 5db notch at 5k is created as a result of just summing them in a traditional way. Very uneven response above 2k.

This is the same exact situation, but both diaphragms are "virtually" alligned by adjusting the time delay between the two. The omni response is much smoother. It sounds much better, and off axis sound is way more even regardless of angle of incidence.
