Is the Pioneer CS-787 actually "Extra Quality"?
For a speaker manufactured in 1978, absolutely. While they lack the pinpoint imaging of modern monitors, they possess a rare musicality and physical presence that digital speakers often miss. They are a time machine—warm, bold, and unapologetically large.
Rating: 8.5/10 (Deducting points for the recessed mids and heavy weight). Best for: The listener who has a big living room, a big amplifier, and a love for the golden age of hi-fi.

The Pioneer CS-787 speakers are a notable example of vintage hi-fi engineering, often praised for their balance of power and classic aesthetic. While many mid-level floorstanders of their era utilized simpler internal builds, the CS-787 model was designed to offer "extra quality" through its robust driver configuration and cabinet design. 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
While some critics categorize standard vintage floorstanders as "simple boxes," the higher-tier Pioneer CS series is respected for its durability and reliability over decades. They are frequently cited as a preferred choice for audiophiles looking to upgrade from factory-standard systems to a more professional, high-fidelity environment without the extreme price tag of modern boutique gear.
The Pioneer CS-787 is a 3-way bass reflex loudspeaker system manufactured in Japan, typically dating back to the late 1980s or early 1990s. While often marketed as "vintage," community feedback from forums like Reddit and AudioKarma generally classifies them as mass-market speakers rather than high-end audiophile gear. Key Specifications According to technical data from Hifi-Wiki and Hi-Fi-Zone: System Type: 3-way, bass reflex Power Handling: 50W (Nominal) / 80W (Music) Impedance: 6.3 Ohms Frequency Response: 40 Hz to 20,000 Hz Drivers: Woofer: 200 mm (8-inch) cone Midrange: 77 mm cone Tweeter: 66 mm cone Dimensions: Approximately 560 x 320 x 230 mm
The Pioneer CS-787 speakers are often remembered as a hallmark of the 1980s "kabuki" speaker era—a period characterized by large cabinets, multiple drivers, and an imposing visual presence. While some audiophiles debate the nuances of their frequency response, the "Extra Quality" designation associated with this series represents a specific peak in Pioneer’s consumer-grade high-fidelity engineering.
For those looking to build a vintage setup or restore a pair of these towering units, understanding what makes the CS-787 stand out is essential. Technical Architecture and Driver Array
The Pioneer CS-787 is a 3-way bass reflex system designed to handle the high-output demands of 80s integrated amplifiers. The "Extra Quality" build refers to the reinforced internal bracing and the specific material composition of the drivers.
The Woofer: Typically featuring a 12-inch (30cm) cone, the woofer is designed for punchy, rhythmic bass. It uses a corrugated surround which, unlike foam, resists rot over decades.
The Midrange: A dedicated 4.7-inch cone handles the vocal frequencies, ensuring that the heavy bass doesn't "muddy" the lyrics or lead instruments.
The Tweeter: A 2.6-inch cone or dome tweeter provides the high-end sparkle. Pioneer tuned these for clarity, making them excellent for rock and electronic music of the era. Sound Profile: The "Extra Quality" Experience
When enthusiasts talk about "Extra Quality" in the context of the CS-787, they are usually referring to the speaker's efficiency and power handling.
Sensitivity: These speakers are highly sensitive, meaning they don't require a massive modern amplifier to reach high volumes. Even a modest 30-watt vintage receiver can drive them effectively.
Soundstage: Due to the wide baffle design, the CS-787 projects a massive wall of sound. While they may not have the "pinpoint" imaging of modern bookshelf speakers, they excel at filling large rooms with energy.
Durability: The "Extra Quality" moniker is earned through the longevity of the components. Many CS-787 units found today still feature original drivers in working condition, provided they haven't been pushed past their thermal limits. Key Specifications at a Glance Type: 3-Way, 3-Driver Loudspeaker System Frequency Response: 35Hz to 20kHz Power Handling: 120W (Peak) Impedance: 8 Ohms Enclosure: Bass Reflex (Ported) Finish: Simulated Wood Grain / Black Ash Tips for Restoration and Maintenance
If you have acquired a pair of Pioneer CS-787s, a few small steps can significantly enhance their performance:
Capacitor Replacement: The electrolytic capacitors in the crossover are now 40 years old. Replacing them with modern film capacitors will "open up" the high end and restore lost clarity.
Cabinet Sealing: Check the rear panel for air leaks. Resealing the joints with wood glue or silicone can tighten the bass response.
Placement: These speakers perform best when placed on short (6-10 inch) stands tilted slightly upward. This aligns the tweeter with your ears and reduces "boomy" bass reflections from the floor. Verdict: Is the CS-787 Still Relevant?
The Pioneer CS-787 "Extra Quality" speakers are perfect for the listener who values the aesthetic and "big sound" of the golden age of Hi-Fi. They are not clinical studio monitors; rather, they are "fun" speakers designed to make music feel alive and physical.
Whether you are spinning vinyl from the 80s or streaming modern tracks through a vintage tube amp, the CS-787 remains a testament to Pioneer's ability to blend industrial durability with classic Japanese acoustic design.
What amplifier or receiver are you planning to use with them?
What is the size of the room where you'll be setting them up?
To understand the "Extra Quality," we must look at the raw data. The Pioneer CS787 is a 4-way, 4-speaker bass-reflex system. Here are the vital statistics:
The standout feature here is the cloth surround on the 12-inch woofer. Unlike foam surrounds that rot after 20 years, cloth surrounds (impregnated with a sticky sealant) last for decades. This is a primary reason the CS787 has survived in "Extra Quality" condition today.
The CS-787 arrived at the tail end of the “Kabuki” speaker era (mid-to-late 1970s). This was a time when Japanese manufacturers competed to see how many drivers they could fit on a single baffle. The CS-787 is no exception.
At first glance, these towers are intimidating. They feature a massive 15-inch woofer, a 5-inch midrange, a horn tweeter, and a super tweeter. That’s four drivers per cabinet. The wood veneer (often walnut) is thick and luxurious, and the grille cloth is that iconic brownish-yellow weave that screams "1978."
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.
Final Verdict: Highly recommended. A true diamond in the rough.
