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, the Bass550 Subwoofer may
differ in some respect from its published specifications and descriptions, but will always equal or exceed the original
specifications unless otherwise stated.
