This is how this speaker works as a microphone. I simply connected it to a microphone input on my mixer (with the phantom power off) and set the input gain to maximum. I’m surprised at how much it still sounds like a tweeter, even when operating as a microphone. I expected it to have more bass response, considering the diaphragm is 1 and ¾ inches in diameter. You may also notice the recording picked up a radio station in the background. This was probably due to the lack of shielding, and the speaker was never meant to be used as a microphone.
