The Pioneer CS-522A is a floorstanding loudspeaker designed for home audio systems. Launched in the 1970s, it features a three-way speaker design meant to provide a full-range sound experience. The speaker includes a 12-inch woofer for deep bass response, a 5-inch midrange driver for clear vocals and instruments, and a 2-inch cone tweeter that extends the high frequencies for a balanced audio performance. With a frequency response typically ranging from around 30 Hz to 20 kHz, the CS-522A is capable of handling a wide range of audio content, delivering punchy bass while maintaining clarity in the mids and highs. The speaker is also equipped with a sensitivity rating that allows it to produce a considerable volume with relatively low power input, making it suitable for various amplifiers. The cabinet is usually constructed from durable materials and often features attractive wood veneer finishes, allowing it to blend aesthetically with home environments. It is designed to be used in stereo or surround sound configurations and can handle a broad range of musical genres effectively. The Pioneer CS-522A has garnered appreciation for its build quality and audio performance during its production run, making it a popular choice among audio enthusiasts of the era.
