Pioneer Cs787 Extra Quality Fixed

The Pioneer CS-787 speakers are often remembered as a hallmark of the 1980s "kabuki" speaker era—a period characterized by large cabinets, multiple drivers, and an imposing visual presence. While some audiophiles debate the nuances of their frequency response, the "Extra Quality" designation associated with this series represents a specific peak in Pioneer’s consumer-grade high-fidelity engineering.

Tweeter: Paper cone tweeter for high-frequency reproduction. Frequency Response: 40 Hz to 20 kHz.
