TU Series driver units feature newly developed diaphragms employing special heat-resistant polyimide film to prevent the diaphragm from absorbing moisture and changing shape, as well as to improve the low frequency characteristics. High speaker efficiency has also been realized by nimizing the gap produced when the diaphragm bobbin is installed in the magnetic circuitry slit. High-impedance models are equipped with an input impedance selector switch which facilitates mpedance settings without requiring disassembly. The switch is also equipped with an OFF position to prevent speaker damage resulting from incorrect impedance setting.
