The JBL 2152H Coaxial Transducer
represents the results of JBL’s intensive research into the performance
and applications of compressiondriver coaxial transducers intended
for engineered sound applications. TO
achieve high acoustical power output
capability while maintaining smooth
response, wide bandwidth and consistent dispersion in several critical
HF octave bands, JBL engineers used
advanced CAD techniques to apply
low-distortion Bi-Radial® horn
architecture to a coaxial system, and
then combined the new horn with
JBL’s 2416H High-Frequency Compression Driver.
The 2416H incorporates a pure
titanium diaphragm with JBL’s
patented “diamond surround” for
control over secondary resonances,
extended frequency response, and
greatly reduced mechanical fatigue.
A copper shorting ring on the pole
piece controls high-frequency impedance and further improves highfrequency response.
The low frequency driver combines
a rugged die-cast frame with a specially designed cone and 76 mm (3 in)
edge-wound aluminum ribbon voicecoil motor structure. An integral
transformer mounting bracket is preattached to the LF transducer frame
and also allows quick access to the
crossover network.

2152H 300 mm (12 in) Coaxial Transducer
In response to consultant and contractor requests, the
JBL 2152H was designed to perform well in the most
commonly-specified utility metal enclosure and baffle
combinations, despite the generally detrimental acoustical
properties of those enclosures. Custom-build boxes will
usually result in better performance characteristics than
those published here.

JBL continually engages in research related to product improvement. New materials, production methods, and design refinements are introduced into existing products without
notice as a routine expression of that philosophy. For this reason, any current JBL product
may differ in some respect from its published description, but will always equal or exceed
the orignal design specifications unless otherwise stated.
