The 5000-series
screen loudspeakers bring together several of JBL’s advances over recent
years. Since the high frequency section of the system works only above 2500
Hz, it has been redesigned with Optimized Aperture high frequency horns and
drivers, resulting in distortion that
is 8 to 10 decibels lower than the
previous designs.

A new midrange
horn and driver have been introduced into the cinema loudspeaker art,
providing controlled output over the critical range from 300 Hz to 3000 Hz.
This is a true compression driver design -- not a horn-loaded cone
driver.JBL’s Vented Gap Cooling low
frequency transducers are used to ensure cool operation with low power compression over long operating
periods.

Digital signal
processing is used to provide all aspects of frequency division, time
correction, and system power response and room equalization. Preset tunings
for the 5000-Series are included.

All components
of the system have matching radiation patterns at the crossover frequencies;
this contributes to uniform coverage and smooth power response in the cinema.
