New lineup to evolve
FE83-Sol is a special full-range driver unit inheriting its own technology and development philosophy of FE103-Sol and it has been developed
based on FE83En. Quality of mid-high frequency sound is further improved by two-layer paper-making and low distortion ferrite outer magnet
circuit, and it offers higher resolution with delicate and articulate music reproduction. In addition, the newly designed damper has excellent
linearity, even at a very low level input, it accurately follows the change of the input signal. Frame color is the same copper orange as the
FE103-Sol, which expresses our passion and own technology to build sound. Please enjoy the newly evolved lineup of FE83.
●ES cone diaphragm with Two-layer paper-making
Based on the cone paper of FE83En, combining smooth high density ES cone using fine pieces of fiber with two-layer paper-making*, it
achieves light weight but further high stiffness and high internal loss. The base layer is mainly built with the long fiber pulp to offer high stiff-
ness and internal loss, and the surface layer is built with short fiber pulp to enhance the propagation speed of cone paper surface. Due to this,
while keeping bright and high tension mid range sound as is, it has enabled sharp high frequency with good response and rich low frequency
reproduction.
*Two-layer paper-making is; making a piece of diaphragm in two steps process with our unique paper-making technique that consists of base
layer and surface layer.
●High compliance corrugation damper
In order to improve linearity, it uses a superior corrugation damper; although being high compliance, it has consistency in hardness regardless
of input level from small to large and offers excellent movement.
●Low distortion ferrite outer magnet circuit
The magnetic circuit has secured a sufficient magnetic flux density by using Ø65 mm ferrite magnet. The magnetic circuit has achieved to
reduce the current distortion by placing the copper cap to the peripheral portion of magnet and the pole piece, and to improve the clarity of the
mid-high frequency with thorough low distortion of the drive system.
●Mechanical 2 way center cap/high heat resistance glass composite voice coil bobbin
Center cap is located as directly mounted to the voice coil bobbin to offer wider high frequency reproduction and achieves over 20 kHz
frequency range. Also, the voice coil bobbin ensures transmitting the vibrations to center cap by employing glass fiber and phenol resin sheet
that has high Young ratio.
●3-point bonding method
It uses a three-point bonding method, which adhere the cone paper, the damper and the voice coil in the same place. High frequency response is
improved by increasing the strength of neck of cone.
●Fasten #205 gold plated terminal
It uses fasten #205 low loss gold plated speaker terminal. It ensures speaker cable connection and avoid sound quality deterioration.
