Many different types of speakers exist, making choosing the right one for the job a difficult task. Making the right choice involves balancing several factors including size, sound quality, efficiency and power handling. A typical speaker is made up of several components. One or more drivers are mounted in a cabinet , generally made out of wood or plastic. There are many kinds of drivers, each suited to reproducing a particular range of sound.
Midrange drivers reproduce the sound in the middle of the audible frequency spectrum.
Some speakers contain two or three drivers that can respond over much of the audible frequency spectrum. These speakers are often called full-range speakers. Other designs exist in which indivual cabinets house drivers, but the whole speaker is not capable of reproducing the entire audible frequency range. For example, it is common to find two-cabinet speaker setups. One cabinet houses a tweeter and a mid-range driver, while a second cabinet houses a woofer.
