There are several different types of speakers and sound imaging. Coaxial or three ways, two or more units are built in the same frame. This is an inexpensive and easy to install. Individual speakers, woofers and tweeters are an external crossover, which can be used experimentally to perfect placement. Horn is a type of speaker, great for guiding sound and very effective. Mid-bases and Sub woofers add bass system.
