A Legacy of Audio Innovation: The History of Pioneer
Pioneer’s journey began in 1938 in Tokyo, founded by Nozomu Matsumoto as a humble radio and speaker repair shop. This marked the inception of a brand that would become synonymous with audio excellence. A pivotal moment arrived in December 1953 when Mr. Matsumoto achieved a breakthrough, developing the first domestic dynamic speaker crafted entirely from original parts. Named the A-8, it was launched in Japan under the Pioneer brand, laying the foundation for Pioneer’s enduring legacy in HiFi audio. The Pioneer CS-77A is a direct descendant of this pioneering spirit, embodying decades of audio innovation and expertise. Read More about Pioneer’s History.
