the hi-fi world) - designed specifically
to reproduce mid frequencies
(typically above 500 Hz). The highest
frequency reproduced by a
midrange unit is usually not higher
than 6 kHz. If a cone-type driver is
used as a midrange loudspeaker, its
diameter typically ranges from 5 to
12 inches; if a compression driver is
used, its diaphragm diameter may
range from 2.5 inches to 4 inches
(with a few special units up to about
9 inches in diameter).
