Pioneer PW-A38

Commentary

A series 38 cm cone shaped woofer.

The cone paper is made of carefully selected fiber material with high Young's modulus and moderate internal loss.
In addition, high compliance type roll edge is adopted for the edge.

Magnetic circuit using large ferrite magnet is adopted.
The voice coil uses a long voice coil with high magnetic efficiency and uniform magnetic flux even at large amplitude.
