Full range car speakers or multi-axial car speakers are available in assorted shapes and sizes which usually correspond with mounting requirements for the intended vehicle. These include non-circular cone shapes, such as square, oval, or even triangular and varying sizes including 4", 5.25", and 6.5" for circular speakers; or 4" x 6", 5" x 7" and 6" x 9". In most current car audio applications, speakers are mounted in certain common locations including the rear deck, the kick panel, front dash, or the doors.

Usually, a set of components (or separates) includes a pair of tweeters, a pair of mid-bass drivers and a pair of crossovers to limit the frequency range each speaker must accurately reproduce. The mid-bass woofers supplied with a component car speaker setup are physically separated so the tweeter, which is very directional, can be placed in an optimal position, usually on the dash facing the listener, while the larger mid-bass driver can be placed where there is room, usually in the front dash or door panels.

Tweeters used in car audio systems are small loudspeakers designed to produce high frequency audio output, typically from around 2,000Hz to 20,000 Hz (which is typically considered to be the upper limit of human hearing). Some tweeters can manage response up to 45 kHz. The name is derived from the high pitched sounds, or tweets, made by some birds. Tweeters are sold separately to allow you to take full control of your experience by allowing you to tailor the it to your tastes.

Mid-bass drivers, also known as Mid-range Speakers or Mid-basses, are car audio loudspeakers that re-produce mid to low audio frequencies typically around 80 Hz to 500 Hz. Mid-Bass speakers are used to build component-type systems where each car audio component, like tweeters, mids, and subwoofers are all chosen separately and are properly matched to produce the highest level of performance.
