Pioneer PAX-A30

Commentary

A series 2-way coaxial speaker unit.

A 30 cm cone type woofer is used for the low range.
Ferrite magnets are used for the magnetic circuit, and high-compliance cone paper with roll edges, large dampers, and voice coils made of aluminum wire with a wide winding width are used for the vibration system. These measures improve the linearity against amplitude and the distortion at large input.

A wide-angle cellular horn is used for the high frequency band, and the directional characteristics are improved by an equalizer installed in front of the diaphragm.
