2145 300-mm (12-in) Composite
An integrated system consisting of a 300.mm
(Gin) low frequency loudspeaker, separate
50-mm (2.in) high frequency direct radiatorand
3-kH2 frequency dividing network Often used as
a monitor system in limited space applications.
its frame is shallow enough to allow installation
within wall or ceiling structures for distributed
music and paging systems.
2150 380-mm (15-in) Composite
Ideally suited for maximum intellrgrbrlrty,high
level paging systems and distributed reinforcement in large areas. It consists of a 380-mm
(15-in) low frequency loudspeaker and a
130.mm (5-in) direct radiator integrated on a
singleframe.The 2150 may be installed in ported
enclosures or in a 4530 low frequency horn.
[The 3125, a 1200.Hz network, is optional.)
2105 130-mm @-in) Speech Range
A powerful midrange loudspeaker providing
high acoustic output, smooth response and wide
drsperston Well suited for in-line arrays and
distributed cerlrng installations for naturolsounding paging systems or limited bandwidth
musrc reproductionThe 2105 is also useful as a
midrange dnver in medium efficiency monitor
systems.
2115 200-mm (a-in) Full Range
Natural wide-range performance with peakfree response and freedom from distortron
through more than eight octavesThe 2115 can
be used in distributed systems as a single-unit
monitor or in column array for moderate level,
high quality reinforcement

JBL Professional Series extended range loudspeakers are rugged, precrsion transducers for
use in custom ltne arrays, distributed source
installations and general applrcatrons. Frequency range extending through the major
portion of the audio spectrum allows their use
as single-driver systems, for reproduction of the
extreme high frequencres each may be augmented by a compressron driver equrpped with
the appropriate horn and acoustic lens These
drivers incorporate precisely machined. highly
efficient magnetic assemblies, large edgewound alumrnum voice coils. and shallow.
