AC566 is a compact 2-way full-range loudspeaker 
system comprised of one 384 mm (15 in) low 
frequency driver and one 25 mm (1 in) exit/35 
mm (1.5 in) voice-coil compression driver. e 
horn provides 60° by 60° coverage in vertical and 
horizontal orientation. High-slope passive crossovers 
minimize band overlap and well-controlled oaxis 
response.
e cabinet is tted with M10 threaded suspension 
points. Four threaded inserts located on back of the 
enclosure allow attachment of a MultiMount® or 
similar type mounting. 
AC566 is part of JBL’s AE Application Engineered 
Series, a versatile family of loudspeakers for a wide 
variety of xed installation applications.
JBL continually engages in research related to product improvement. Some 
materials, production methods and design renements are introduced into 
existing products without notice as a routine expression of that philosophy.

its published description, but will always equal or exceed the original 
design specications unless otherwise stated.
