AC266 is a compact 2-way full-range loudspeaker
system comprised of one 310 mm (12 in) low
frequency driver and one 25 mm (1 in) exit/35
mm (1.5 in) voice-coil compression driver. The
horn provides 60° by 60° coverage in vertical and
horizontal orientation. High-slope passive crossovers
minimize band overlap and well-controlled offaxis
response.
The cabinet is fitted with M10 threaded suspension
points. Four threaded inserts located on back of the
enclosure allow attachment of a MultiMount® or
similar type mounting.
AC266 is part of JBL’s AE Application Engineered
Series, a versatile family of loudspeakers for a wide
variety of fixed installation applications.

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 original
design specifications unless otherwise stated.
