Illuminati (33rd Degree)

The wavelength of 12kHz is an inch and an eighth. So naturally, a quarter wavelength is about a quarter inch. Alignment really has little meaning at that scale, since diaphragm dimensions are larger. Best thing is to shoot for a dense interference pattern, where there are literally so many interference nodes that the sound field balances out.
