JBL continually engages in research related to product improvement.
New materials, production methods and design refinements are intro-
duced 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.
