*The maximum recommended amplifier power rating will ensure proper system headroom to allow for
occasional program peaks. We do not recommend sustained operation at these maximum power Levels.
JBL continually strives to improve its products. New materials, production methods and design refinements
are introduced into existing models without notice as a routine expression of our design philosophy. For this
reason, JBL LXE Series Loudspeakers may differ in some respect from their published specifications
and descriptions, but will always equal or exceed the original specifications unless otherwise stated.
