Pioneer 63DX (1970–1976)
A 4-way, 6-driver loudspeaker system from Pioneer’s early high-fidelity lineup.
Overview
The Pioneer 63DX, also known as the CS-63DX or CS.63DX, is a floor-standing loudspeaker system produced between 1970 and 1976. Pioneer marketed it as a high-performance system. It uses an infinite baffle enclosure and, for its era, a complex driver array. Each speaker houses six drivers in a 4-way configuration, including dual 130 mm midrange cones, horn tweeters, and dual horn super tweeters. Each cabinet weighs approximately 63 pounds. It was built for serious audio enthusiasts who wanted extended frequency response and dynamic range.

Design
