Why Are Coaxial Speakers Used for Car Rear Doors?

[EzraAnn]

Car rear doors are equipped with coaxial speakers because they can save the need for an additional tweeter. A coaxial speaker is a type of speaker that combines both tweeter and woofer functions, featuring two speakers mounted on the same axis—one responsible for reproducing high frequencies and the other for mid-low frequencies. Additionally, the diaphragms of these two speakers must overlap. Due to their physical positioning being nearly at the same point, they effectively resolve phase deviation issues. Extension: Speakers serve as the audio signaling devices in cars. During driving, the driver can emit necessary sound signals as required or mandated to warn pedestrians and alert other vehicles, ensuring traffic safety. They are also used for urging movement and transmitting signals.
