3-Way Car Speakers

Three-band car speakers are a system where the audio signal is divided into three separate frequency bands. Each band is then reproduced by a dedicated transducer, which is the part of the speaker that physically produces the sound. The reason for this division is that a single transducer cannot effectively play the entire audible spectrum from deep bass to the highest notes. In a three-band system, therefore, the tasks are divided. The lowest frequencies, i.e. the bass, are handled by a large woofer, referred to as the "woofer". The middle frequencies, which include, for example, human voices and most musical instruments, are handled by a separate midrange speaker. The highest frequencies, such as cymbal sounds or hisses, are handled by a small tweeter, or "tweeter". A device called a frequency switch takes care of directing the different parts of the signal to the correct transducers. This acts as a filter to ensure that each transducer receives only the frequencies for which it is designed. The result is a cleaner, more detailed sound as each transducer operates in its optimum range without unnecessary distortion.
