Note: Do not pay "vintage hype" prices. The CS-787 is not a rare TOTL (Top Of The Line) model like the HPM-100. It is a solid, mid-tier consumer speaker. Over $400 is too much unless they are mint with original boxes.
Modern speakers often use two drivers. The CS-787 uses five. Why?
The result is a speaker that tries to do everything. Whether it succeeds is a matter of debate.
The Pioneer CS-787 is more than a speaker; it is a historical artifact of when audio was trying to be grandiose. In an era where speakers are shrinking and becoming smart, the CS-787 remains gloriously dumb, heavy, and loud.
If you find a pair at a garage sale or estate sale for under $300, grab them. Re-foam the woofers, recap the crossovers, and connect them to a 1970s receiver. Close your eyes, put on Dark Side of the Moon, and you will understand why people still chase this vintage sound.
They don’t make them like this anymore. And frankly, that’s a shame.

The Pioneer CS-787 is a vintage 3-way bass reflex loudspeaker system produced by Pioneer in the mid-1980s. Known for its punchy audio and classic wooden aesthetic, this model was part of the broader CS series designed to offer a balance of power and high-fidelity sound for home audio enthusiasts.

reflects the era’s transition toward more efficient manufacturing while maintaining Pioneer's reputation for reliable performance. The cabinets are typically finished with a wood-grain veneer, and the bass reflex design includes a front-facing port to enhance lower-end response.
While some audiophiles note that entry-level CS models from this decade moved from solid wood to chipboard or LDF (Low-Density Fiberboard) construction, the
remains well-regarded for its ability to deliver a powerful, "live" sound without significant loss in quality. Audio Performance Pioneer CS-787
is often praised for its "powerful sound" and "present" midrange.
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.
Mids and Highs: The dedicated cone midrange and tweeter ensure that vocals and instruments remain distinct, avoiding the "muddy" profile found in lower-end 2-way systems. Market Value and Collectibility Today, the Pioneer CS-787 Note: Do not pay "vintage hype" prices
is considered a relatively rare find on the used market. Depending on the condition of the cones and the cabinet's finish, a pair can range from €115 to over €300 (approximately ₹10,000 to ₹27,000). Collectors often look for units with original "net" front covers and intact driver surrounds.
For those building a retro hi-fi setup, these speakers are a "perfect centerpiece," especially when paired with a vintage receiver from the same era.
Pioneer CS-787 is a rare, vintage 4-way speaker system crafted in Japan during the early 1970s, celebrated by audiophiles for its "FB" (Free-Beating) pulp cone drivers and classic walnut craftsmanship. The Story of the Pioneer CS-787
In the golden age of hi-fi, Pioneer engineers sought to create a speaker that could handle the warmth of vinyl while maintaining structural integrity over decades. The result was the CS-787, a "bookshelf" powerhouse that bridged the gap between fine furniture and precision audio engineering. The "FB" Innovation
: Unlike standard paper cones, the CS-787 utilized specialized "FB" pulp material in its 12-inch woofer and midrange drivers. This material was engineered to be stiffer with superior damping, producing a natural, "non-boomy" bass and an outstanding midrange presence that made vocals feel live in the room. Built to Last
: At a time when many speakers suffered from foam rot, Pioneer used high-quality cambric surrounds
for the drivers. This choice ensured that the CS-787 would not deteriorate, allowing many original units to remain in excellent condition today. The 4-Way Architecture
: It wasn't just about the bass. The system featured a complex 4-way design: : 12-inch cone for deep, solid lows. : 5-inch cone for clear presence. : 3-inch cone for crisp highs. Super Tweeter The result is a speaker that tries to do everything
: A multicellular horn type for ultra-high frequencies up to 20,000Hz. Aesthetic Presence
: Encased in hand-finished genuine walnut with a pleated saran grille, the

Unlike the "shouty" midrange of some JBLs, the CS-787’s dedicated cone midrange is surprisingly polite. Vocals sit slightly forward but remain smooth. Electric guitars (think David Gilmour) have that creamy, saturated distortion that fills the room without piercing your ears. This is where the speaker punches above its weight class.
If you are hunting for a pair today ($300–$600 depending on condition), here is your checklist:
Walk into a vintage audio shop and you’ll spot the CS-99A immediately—it’s flashy. The CS-787 is the opposite. It is massive (25.5" H x 15.5" W x 12.75" D) and heavy (over 45 lbs). The cabinet is finished in a genuine walnut veneer that, when oiled, glows with a warm, furniture-grade luster.
The grille is a simple, dark brown cloth—unadorned. No lattice work. No badges screaming "Super Tweeter." Underneath that cloth, however, is the magic.
Let’s be brutally honest. For $1,500, you can buy a pair of modern bookshelf speakers (like the KEF LS50 Meta) that will out-resolve the CS-787 in clarity, imaging, and neutrality.
But here’s the catch: Those modern speakers require a $1,000 subwoofer and a $2,000 amplifier to match the visceral effortlessness of the CS-787.
The Pioneer was built for fun, not for a mixing desk. They are enormous, inefficient with space, and colored. But they are also holographic, warm, and capable of playing at party volumes with a 30-watt receiver.
