Commentary
25 cm cone type full range unit of FP series
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.
With a 25 cm aperture, the FP253 has naturally extended high-frequency characteristics, efficient and roomy bass, good mid-to-high range, and can be upgraded by adding tweeters.
