Full-range speaker

A full-range loudspeaker drive unit is defined as a driver which accepts and reproduces as much of the audible frequency range (20 Hz to 20 kHz) as possible, within the limitations imposed by the physical constraints of a specific design. The frequency range of these drivers is maximized through the use of a whizzer cone and other means. Most single driver systems, such as those in radios, or small computer speaker designs, cannot reproduce all of the audible frequencies or the entire audible audio range (i.e., sound within the range of human hearing).
