Happy to recently find the Bagby white paper on how to measure in-room responses with OmniMic. When measuring near field response, how far away should the microphone be when you have a driver with a phase plug? For example, I have some TB W4-1337SDF full range, 4" speakers. Per Jeff's recommendation the mic would need to be 1/10th the distance of the radius of the radiating area. In the case of these W4's, there's a phase plug protruding from the center much farther than the recommended distance from the actual cone. Also wondering what impact a phase plug may have on near-field measurements in general... Thanks guys!
