Blog Title: Rediscovering a Gem: The Pioneer CS-787 “Extra Quality” Speakers
Published by: Vintage Audio Archives Date: April 19, 2026
If you are a fan of vintage Japanese hi-fi, you know that Pioneer rarely did things by half measures. But even among their legendary lineup of loudspeakers, a specific model stands out for its unique naming convention and surprising sonic prowess: the Pioneer CS-787 "Extra Quality."
Let’s be honest—slapping the words “Extra Quality” on a speaker grille is a bold move. It invites scrutiny. Does it live up to the boast? After spending a few weeks with a restored pair, the answer is a resounding yes, but with a few vintage caveats.
This is where the CS-787 divides opinion.
The Pros:
The Caveats (Vintage Character):
The most striking visual feature is the driver arrangement. The large 12-inch woofer handles the low-end with surprising agility. Unlike modern subwoofers that aim for rumble, this woofer focuses on punch and texture—ideal for rock, jazz, and acoustic bass.
The twin tweeter array (a dome and a horn supertweeter) was Pioneer’s solution to the “air band” issue of the era. The standard tweeter covers up to 18 kHz, while the horn extends to 22 kHz, adding sparkle to cymbals and harmonics without harshness.
The Pioneer CS787 Extra Quality is a paradox. In raw measurements, modern KEF or Elac speakers are flatter and more neutral. Yet, nostalgia and physicality matter. These speakers are not analytical tools; they are musical instruments.
For under $400 (typical used market price), you get:
If you are pairing these with a vintage Pioneer receiver (SX-780, SX-980, SA-8800), the synergy is undeniable. They create a "living room concert" experience that modern slim towers simply cannot replicate.
The "Extra Quality" label was justified in 1978, and it remains justified today—provided you find a pair that hasn't been abused. For the collector, the tinkerer, or the revivalist, the Pioneer CS787 is a gateway into high-end vintage audio without the high-end price tag.

Key Features & Performance
Three-Way Driver System: These speakers typically feature a large woofer (often 10 or 12 inches), a dedicated midrange, and a high-performance tweeter. This configuration allows for a broad frequency response, ensuring that deep lows and sparkling highs are handled by specialized drivers.
High Sensitivity: Known for their efficiency, Pioneer speakers of this class often have high sensitivity ratings (typically above 90 dB). This means they can produce a loud, clear sound even when paired with lower-wattage vintage amplifiers.
Audio Character: The CS-787 is valued for its "warm" vintage tone. Unlike modern speakers that can sometimes sound clinical, these offer a rich, immersive listening experience that is particularly well-suited for vinyl records and classic 2-channel stereo setups.
Build & Aesthetic: The "extra quality" is often visible in the cabinet finishing. Featuring classic wood-grain veneers and the iconic Pioneer lattice or mesh grilles, they serve as both high-end audio equipment and a statement furniture piece for any listening room. Why They Stand Out
