Key specifications (reported)

The Cabinet

The first thing you notice is the real wood veneer. In the 1970s, "vinyl wrap" was for budget gear. The CS-787 boasts genuine walnut or oak wood grain. The front baffle is covered in a dark brown felt-like material, which serves a dual purpose: it looks retro-cool, and it reduces sonic reflections off the cabinet face. The grille is a removable, thick cloth frame that snaps into place with plastic pegs (which, unfortunately, are often broken on units found today). The Pioneer CS-787

The Overachieving Underdog: Revisiting the Pioneer CS-787 Loudspeakers

In the golden era of hi-fi, roughly from the mid-1970s to the early 1980s, Pioneer was a titan. They gave us the legendary SX-series receivers, the unkillable PL- turntables, and the iconic HPM-100 speakers. But nestled quietly in the catalogs of 1979, priced just below the flagship HPM models, sat a curious and often overlooked beast: the Pioneer CS-787. The 16" Woofer: This is the heart of the system

Low End: The 200 mm woofer provides solid bass that, while not reaching the subterranean depths of 15-inch models like the Pioneer CS-99A, is more than sufficient for rock and jazz in average-sized rooms.

  1. The 16" Woofer: This is the heart of the system. It moves a massive amount of air, giving you visceral, chest-thumping bass without a subwoofer. It handles frequencies up to 500Hz.
  2. The 5" Midrange: Covers the critical vocal and guitar range. Unlike two-way speakers that force a woofer to play too high, this dedicated midrange keeps vocals smooth.
  3. The 3" Tweeter: Handles standard high-hats and cymbals.
  4. The Horn Super Tweeter (x2): Yes, there are two super tweeters. One is a dome, one is a horn. They kick in above 7,000Hz and 12,000Hz respectively, adding "air" and sparkle to the extreme high end.
