A coaxial speaker is a speaker system in which the individual driver units radiate sound from the same or one point. Commonly known as two-way coaxial speaker, it comprises of a woofer and a tweeter installed together in a single speaker frame. The woofer is responsible to reproduce the bass and midrange frequencies, while the tweeter reproduces higher frequencies. There are also three-way speakers which have a separate bass woofer, midrange driver and a tweeter mounted together. Sound quality and depth can be increased with additional tweeters, but a speaker is also only as good as its individual components. For instance, a low cost three-way speaker will not sound as good as a high quality two-way speaker.
