Array Series Systems
JBL’s commitment of providing audio
professionals the best tools for their
work continues with the Array Series.
JBL Array Series systems provide the
ultimate performance for touring and
fixed installations. The high power,
compact 4894-90 provides smooth,
predictable coverage and response
from a single box. It combines ease of,
transport with the flexibility to fly or
install quickly and safely. Integration
of advanced design high power trans-
ducers, a new generation of horns,
and advanced control electronics pro-
vides clearly superior performance.
Reliability is designed in, without
having to relay on intrusive signal
processing.
Components
Array Series builds upon a solid foun-
dation: more than 40 years of JBL
transducer expertise and engineering.
The 355 mm (14 in) low frequency
transducer represents JBL’s commit-
ment to research. New technology
includes a unique deep copper-
sleeved gap low-distortion motor
structure topology, coupled to Vented
