The driver system in the Meze LIRIC combines individual switchback and spiral shaped voice coils within the same diaphragm, allowing sound to be targeted with more accuracy around the natural form of the ear, for a more selective acoustic performance. SWITCHBACK COIL: The switchback coil is more efficient at reproducing lower frequencies and is positioned in the upper part of the driver. SPIRAL COIL: The spiral coil is more eﬃcient at reproducing middle-high frequencies and is positioned directly over the ear canal, enabling more direct sound waves to enter the ear without any time delays.
