Kind of a silly/simple question: Are the diagonal cuts on the side of the various AKG ck9x mics cosmetic or are they part of the design? I know that you never want to cover the side vents when using a directional mic as it will change the polar pattern of the mic, so I want to be sure my planned methods for mounting these won't cause that problem. For instance, in order to fit them into a kwon bar, I was going to wrap that area with a furniture glider to make it fit more snugly. It seems to me like those diagonal cuts are a lot farther down the cap's body than the side vents on other types of mics, so I thought maybe they were cosmetic only. Also, the omni has one cut, and AFAIK omnis don't need side vents, so that also added to my confusion. Thanks for answering such a simple question.
