Commentary

A speaker system developed to maximize the potential of music while focusing on the physical characteristics of reproduced sound.

A 25 cm cone type woofer is installed in the low range.
Designed for low-range stretch and damping, it uses a large magnetic circuit, a damper with unique shape and good linearity even at large amplitude, and a free edge molded from carefully selected materials.
Corded curved cones are used for the cone paper, which is important for determining sound quality. It is designed to suppress the rise of the high-frequency resonance point by a curve with a large radius, and at the same time provide rapid attenuation at unnecessary frequencies.

Equipped with 12 cm cone type skoker in the middle area.

A horn type tweeter newly designed for the F-500 is installed in the high range.
A polymer compound with high rigidity is used for the diaphragm, and it is designed to suppress generation of partial vibration which causes strain and to sufficiently increase high resonance frequencies.
A full-scale LC-type network is used for the network section.
In addition, it is equipped with a change-over type level control, and it can be switched in 3 stages of clear, normal and soft.

The enclosure uses a bass reflex system.
A chip board is used for the plate material, the baffle plate and the back plate are assembled with 18 mm thick plates, and the inside is filled with sound absorbing material with excellent sound absorbing effect.
The exterior has a walnut oil finish.
