Pioneer Cs-787 Exclusive

The internal crossover networks use electrolytic capacitors. Over forty years, these components drift in value or dry out, leading to a dull or muffled sound. Replacing the old capacitors with modern film caps will instantly restore clarity and detail.

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.

When they finished, they hauled the towers back to their rightful place. Leo pulled a pristine copy of Kind of Blue from the shelf. He lowered the tonearm.

It wasn't until the HPM series (featuring the legendary HPM-100) came along that the company began specifically engineering their speakers for the international market and Western listening tastes. The CS-787 thus represents an interesting bridge: a classic design from a specific cultural context before the brand fully globalized its tuning philosophy. pioneer cs-787

Because these are older units, prices vary significantly based on the condition of the wood veneer and the original drivers.

To truly appreciate the CS-787's place in the market, let's compare it with two of its well-known siblings:

: As vintage equipment from the 80s, units may require a "tune-up" or inspection of the driver surrounds to ensure they haven't deteriorated over time. The internal crossover networks use electrolytic capacitors

Understanding the raw specifications of the CS-787 helps explain why it pair so well with vintage solid-state amplifiers from the same era.

The is a standout feature, frequently praised for its detailed yet non-fatiguing character. It’s often described as "sweet, precise, and both gentle and accurate," outperforming many modern soft-dome tweeters, which can be too smooth, and metal-dome tweeters, which can be overly bright. This high-quality tweeter is key to the speaker's engaging, long-term listenability.

The aesthetic is quintessential 80s, typically featuring dark wood-grain cabinets and removable front net covers. While some enthusiasts consider this era of Pioneer speakers to be more "budget-friendly" compared to the high-end HPM series, the CS-787 remains respected for its durability and "old school" sound signature.

The selection of drivers reveals a thoughtful approach to sound reproduction. The is designed to handle low frequencies. The 77mm cone midrange is responsible for the critical vocal and instrument fundamentals, and the 66mm cone tweeter handles the highest frequencies, providing air and detail. The 50-watt nominal power handling (with 80-watt peaks) means the CS-787 can be comfortably driven by a wide range of vintage and modern amplifiers, from modestly powered receivers to more robust integrated amps. The 40Hz to 20kHz frequency response indicates a very respectable low-end extension for a bookshelf speaker of its era, aiming to reproduce the full range of human hearing.

Typically rated between 80 to 120 Watts RMS, making them highly compatible with vintage receivers.
