JBL is part of the Harman International family of audio companies, a group

with a common purpose: combining technology with a love of music to

manufacture audio products that provide new levels of satisfaction, perform-

ance and value.

To promote diversity and creativity, JBL operates independently in research

and development. When it comes to translating the results of these efforts

into actual consumer and professional products, JBL draws on the full 

combined strength of the Harman companies, including one of the world’s

most advanced manufacturing facilities. The result of this teamwork is that

JBL’s renowned excellence in engineering is successfully carried through to

each individual product, regardless of its application or price range.

As new audio concepts and technologies are pioneered, the partnership of

JBL and Harman International guarantees that consumer and professional

audio users everywhere will be able to enjoy their full benefits.

JBL continually engages in research related to product development and

improvement. Because of this, new materials, production methods and

design refinements may be introduced into existing products without notice.

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.
