Commentary
FP series 10 cm cone type full-range unit
In the FP series, we have researched and designed the raw material fiber which is the material for sound production in a wide range. The sound production and performance are realized by the strong magnetic circuit using the light and high rigidity cone paper and large magnet.
The FP103 was designed as the latest model of the series and pursues sharp tone, high efficiency, and high frequency characteristics with good elongation.
