Is it necessary to install a tweeter with coaxial speakers?

It is not necessary to install a tweeter with coaxial speakers. Coaxial Speakers: Coaxial speakers, also known as coaxial-type loudspeakers, feature both a mid-low frequency driver and a tweeter on the same axis, responsible for reproducing high and mid-low frequencies respectively. Their advantage lies in significantly expanding the frequency range of a single speaker unit, making them widely used in motorcycle audio systems. Purpose of Adding a Tweeter: To separate the sound by positioning the high frequencies higher up, thereby enhancing the sense of layering. Function of a Tweeter: A tweeter is essentially a high-frequency loudspeaker, primarily designed to reproduce high-frequency sounds. High-Frequency Loudspeaker: A high-frequency loudspeaker is a specialized type of speaker engineered to produce high audio frequencies, typically ranging from about 2,000 Hz to 20,000 Hz. Dedicated tweeters can even deliver frequencies as high as 100 kHz. The term originates from the high-pitched sounds made by certain birds, particularly in contrast to the low-frequency sounds produced by many dogs, with the latter being referred to as low-frequency.
