Ive made many mics but always used speakers or actual mic elements but I always wanted to build one completely from scratch. a thick paper cone is suspended by hair bands in the center two neodymium magnets are inside a xformer with the EI core removed,the output is good only 3 db less than an sm58 but poor response, flat to 1khz then drops off very rapidly over that. the cone doesn't matter I've tried many different materials and sizes and the response is the same I'm assuming its being limited by the coil.I havent used it so im curious how it sounds.
