[QUOTE="Langston Holland, post: 32824, member: 171"] Re: More McCauley M421 Measurements The major differences can be found in the time domain, HF polar response and higher SPL's young grasshopper. :) Some very old measurements I made of a wedge in my living room, mic at ear level and a soon following second arrival from the ceiling. Three separate measurements were made with capsule diaphragms at identical positions and angles. Notice the similarity between the B&K and Earthworks mics relative to the Midas ECM8000 - particularly in the ceiling arrival and the noise floor that follows.
