and local thrift shops are also common places to spot them, as they were widely distributed in the 80s.
While top-tier flagship models now command premium prices at vintage audio auctions, the mid-range bookshelf and floorstanding models from that era, like the CS-787, remain largely underrated—and surprisingly affordable. According to user discussions on dedicated hi-fi forums like Audiokarma, it was widely believed that the CS series was initially engineered to suit "Japanese tastes," which favored a clean, articulate high end and a slightly leaner, more controlled low-frequency response when compared to the more bass-heavy American designs of the same period. For home listeners in Japan, where smaller rooms and acoustic considerations differ from large American living rooms, a speaker like the CS-787 would have been perfectly at home.
Managing a 4-way system requires a complex crossover network. The CS-787 features level controls on the front baffle, allowing the user to adjust the output of the mid-range and high frequencies to compensate for room acoustics—a standard feature in vintage floor speakers that allowed for a degree of customization in the pre-digital equalization era.
The front baffle is dominated by a large 12-inch (300mm) cone woofer, accompanied by a 4.75-inch cone midrange driver and a specialized horn-type or specialized cone tweeter. pioneer cs-787

Inspect the seams of the wooden cabinets. Air leaks can compromise bass response. Standard wood glue or silicone sealant from the inside can resolve any gaps. Buying Guide and Market Value
Thanks to the massive 12-inch woofer, the bass is prominent and carries significant physical impact. It excels at delivering the punchy kick drums of 80s rock, synth-wave, and early hip-hop. However, because the cabinet lacks sophisticated internal damping, the bass can sometimes sound slightly boomy or loose rather than tightly controlled and fast. For home listeners in Japan, where smaller rooms
reflects the manufacturing ethos of 1980s Japanese consumer audio. The Driver Configuration
The CS-787 utilizes a 4-way, 6-driver configuration, a complex arrangement typical of the era’s "more is better" mindset. This configuration includes:
: As vintage equipment from the 80s, units may require a "tune-up" or inspection of the driver surrounds to ensure they haven't deteriorated over time.
The Pioneer CS-787 is a beautiful example of timeless audio design. While it may not match the raw power of later or larger models, it offers something arguably more important for everyday enjoyment: a warm, inviting, and deeply musical sound that makes you want to listen to your entire record collection again.
