This is an educated guess based on 2 things. First, Quam was in the speaker
manufacturing business. Second, back in the good olde days, intercom
systems used a speaker to perform the duties of both a speaker and a microphone.
Therefore, I have to assume that the Permanic Microphone is a permanent
magnet speaker configured to be used as a microphone.
This is a guess, this is only a guess, had this guess is correct, you will
be supplied with additional information by tons of threads. If it is not
correct, you will no doubt be building fires.
