Pioneer PW-25C

Commentary

25 cm cone shaped woofer unit.

APC (Air Press Cone) type cone paper is used for the cone paper to obtain appropriate internal loss and rigidity.

By considering the shape of the pole and yoke, the occurrence of distortion is reduced.

Aluminum die-cast is used for the frame part to prevent resonance and deformation caused by screws.
In addition to the mounting hole of JIS standard, a mounting hole considering cavity effect is provided in the mounting part of the outer circumference.
