For vintage audio enthusiasts, certain model numbers evoke instant nostalgia. The Pioneer CS-787 is one such speaker. Produced during the late 1970s "Golden Age" of hi-fi, these large, floor-standing speakers represent an era when bigger was often considered better.

Whether you found a pair at an estate sale or inherited them from a family member, here is everything you need to know about the CS-787—their design, sound, and whether they are worth keeping today.
