ROCKFORD FOSGATE; FIRST “KLIPPEL VERIFIED”
MANUFACTURER UNDER NEW CERTIFICATION
By Integrating Klippel Equipment and Procedures into its Development
Process, Rockford Fosgate Continues to Innovate Loudspeaker Technology
TEMPE, Ariz. – Dec. 3, 2012 – Rockford Fosgate, the industry leader in high-performance car
audio systems, is proud to announce its compliance with Germany-based Klippel GmbH.
Rockford Fosgate, an early adopter of Klippel products, is the first “Klippel verified”
manufacturer under the new certification standard.
“Inconsistent test equipment and procedures do not provide a standardized means for
advanced product development,” explained Jake Braaten, Rockford’s director of product
development. “Rockford Fosgate stands behind its products’ performance. By utilizing Klippel
equipment, we insure that we meet or exceed our claims and customer expectations.”
Klippel testing, validation, and certification offers a number of benefits for the manufacturer,
industry, and, ultimately, the customer. During development, Klippel analyzers can uniquely
and dynamically measure the behavior of transducers in the large signal domain in order to
determine its performance and reliability. It has the ability to capture voltage, current, power,
and voice coil temperature on multiple channels over time with any stimulus. In production,
SPL, T/S parameters, coil position, and suspension non-linearity can now all be verified on
every unit and batch manufactured. The result is a product manufactured to Rockford’s precise
specifications that typically exceeds industry standards.
Klippel GmbH is an innovative German company founded by Prof. Wolfgang Klippel in 1997 to
produce novel control and measurement systems for loudspeakers. Current developments are
based on the results of loudspeaker research performed over nearly 20 years and published in
numerous scientific papers and patents. Wolfgang Klippel contributed to the development of largesignal
models for loudspeakers which are the basis for digital compensation of the nonlinear
distortion. His pioneering work was recognized by awards of the Audio Engineering Society.

“Klippel equipment has set the new standard for characterizing non-linear behavior, and is the
best tool for revealing root cause of performance and reliability issues in transducers,” added
Drew Kallen, Rockford’s director of loudspeaker engineering. “Being Klippel verified simply
means that Rockford Fosgate has taken all the necessary steps to design, develop, and test
our products, thus providing customers with the highest quality experience available.”
Added Wolfgang Klippel, managing director of Klippel GmbH, “For almost a decade, Rockford
has integrated Klippel into their development and manufacturing of loudspeakers. We are
pleased that they are the first company to have completed all the necessary steps to becoming
a Klippel certified manufacturer.”
