Before handing over cash for a pair of Pioneer CS787 Extra Quality:
The original foam surrounds are almost certainly rotted. Do not play them until refoamed. Buy a specific 12-inch foam kit. The process takes 2 hours per speaker. Replace the dust caps if they are brittle.
Open the back panel of a standard CS787 and an Extra Quality version side-by-side, and the difference is obvious.
Pioneer’s factory in Japan (stamped “Made in Japan”) produced the Extra Quality units in smaller batches, typically between 1978 and 1981. Serial numbers beginning with “XQ” denote the genuine article.
If you find a pair of CS-787s in the wild:
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 CS787 Extra Quality projects a wide, tall soundstage but lacks the laser-focused imaging of modern coaxial designs. Instruments blend beautifully, making it ideal for background listening or large-room filling, but critical near-field monitoring is not its strength.
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: pioneer cs787 extra quality
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.
Final Verdict: Highly recommended. A true diamond in the rough.
