From a modern audiophile perspective, the CS-787 offers a sound profile that is distinctly "vintage."
Based on official documentation, here are the detailed specifications of the CS-787:
The sonic signature of the Pioneer CS-787 is characteristic of the late-70s "West Coast" sound. It favors warmth, punch, and efficiency over the clinical accuracy found in modern studio monitors.
The front face features bright accent trim rings framing the three drivers, giving the unit an appealing look when operated without its protective covers. A shallow bass reflex port located on the lower front baffle assists the 8-inch woofer, allowing air to move freely out of the cabinet to augment low-end response. Removable front net cloth grills are included to protect the paper driver cones from dust and puncture damage. pioneer cs-787
After 45+ years, the electrolytic capacitors in the crossover have drifted out of spec. This makes the sound dull or unbalanced. Replacing these with polypropylene film capacitors is the single best upgrade you can make. It will cost $50 in parts and an hour of soldering.
Large-diameter woofer (typically 10 to 12 inches) designed to move significant amounts of air for low-frequency response.
By the late 90s, the world had gone digital. Plastic surround-sound systems and tiny satellite speakers were the trend. Friends told Leo to "upgrade" to something sleeker, something that didn't take up half the living room. From a modern audiophile perspective, the CS-787 offers
"They’re vintage now, Leo," his neighbor would say. "They're dinosaurs."
The Pioneer CS-787 embodies a time when audio was about delivering a rich, musical experience. With their 3-way, bass-reflex design, high-quality drivers, and robust build, they offer an authentic vintage Hi-Fi experience.

The cabinets are of a , meaning they incorporate a tuned port. This port significantly increases the efficiency of the low-frequency driver, allowing the relatively small 8-inch woofer to produce surprisingly deep and powerful bass for its size.
Highly efficient (typically around 90-92 dB/W/m), meaning they can achieve loud volumes without requiring massive amounts of amplifier power.
