There are several types of speakers you may encounter in a car audio system:
Tweeters: Tweeters are small, high-frequency speakers that produce sound in the upper range of human hearing. They are typically mounted near the front of the car, near the dashboard.
Mid-range speakers: Mid-range speakers produce sound in the middle range of human hearing, between the bass and treble frequencies. They are typically mounted in the doors or dash of the car.
Full-range speakers: Full-range speakers are designed to produce sound across the entire frequency range, from bass to treble. They are often used in factory audio systems, as they are relatively simple to install and can provide good overall sound quality.
Subwoofers: Subwoofers are large speakers that are specifically designed to produce low frequencies, such as bass. They are typically mounted in the trunk or under a seat and require a separate amplifier to power them.
Coaxial speakers: Coaxial speakers are a type of full-range speaker that have the tweeter mounted in the center of the mid-range driver. They are a common choice for factory audio systems due to their simplicity and good overall sound quality.
Component speakers: Component speakers are separate drivers (tweeters, mid-range drivers, and woofers) that can be mounted in different locations in the car. They offer greater flexibility and often provide better sound quality than coaxial speakers, but they are more complex to install.
