Placid Audio Copperphone

The Placid Audio Copperphone, unlike full range high fidelity microphones, operates within a limited bandwidth of frequencies which lends a nostalgic quality to the signal. Some might compare the sound to an AM radio or a telephone. The sound is achieved through a combination of vintage telecommunications components and a mechanical filtering effect. The microphone’s element is rear ported into a hollow resonant chamber. As sound passes through the diaphragm and into the hollow chamber, upper mid range frequencies are accentuated while low and high frequencies are reduced. An everyday example of this mechanical filtering effect can be demonstrated by pressing a paper towel tube up to your mouth and talking into it.
