what's this about? a guy calls me the other day about the jensen mod 8 speaker i have up on CL. i was away from my phone, so he leaves a voice message. he says he's going to make a kick drum mic with it. i've always known that mics and speakers are similar animals, but this one kinda intrigued me. apparently the speaker's design makes little to do with what it can replicate as a mic, vs its frequency response as a speaker? he said it wouldn't matter that it's a guitar speaker and wasn't rated for the frequencies usually applied to subs. this is where i get a little confused. i would see this working really well within a speaker's operating range. BUT i don't see how just reversing the signal can make it duplicate frequencies lower than it was designed for. can anybody shed some light on this for me?
