Effect of multiple crossed tweeters on frequency response

[mixsit]

Curious about this and this seems a good place to ask. Here's a pair of examples -one Bose and a Turbosound ip300 which I am considering.
Seem there would have to be some interference/interaction?

Helpful perhaps. It cardinally seems to indicate rough vertical off axis combing.
To zero in a bit more specifically though is to ask would it not be the expected -unavoidable- trait of drivers arrayed as in the ip300 to have comb filtered interference response?
