Rockford Announces First Customer for New Rockford Acoustic Design(TM) System

Mitsubishi Motors to Install System in Future Production Vehicle

LAS VEGAS, Jan. 6 /PRNewswire-FirstCall/ -- Rockford Corporation (NASDAQ:ROFO) today announced that Mitsubishi Motors North America, Inc. will be the first customer to factory-install the new Rockford Acoustic Design system, which has been designed for the OEM market. Mitsubishi plans to offer the audio system on a future production vehicle and will announce details at an upcoming auto show.

"We are extremely pleased to partner with Rockford to offer a unique premium audio system that enhances our vehicles' ability to thrill," said Mike Krebs, Vice President of Product Management for Mitsubishi Motors North America. "We look forward to soon introducing our customers to the next generation of factory-installed audio systems."

"The Rockford Acoustic Design brand is designed to create an authentic music experience," said W. Gary Suttle, president and CEO, Rockford Corporation. "We combine fundamental acoustic engineering principles -- which we pioneered -- with leading edge technologies to deliver the highest sonic accuracy for the listener. This high-end brand is expected to appeal to mobile audio listeners who want refined sound, maintain a sophisticated, upscale lifestyle and drive luxury vehicles," continued Mr. Suttle.

Rockford Acoustic Design brings together all of Rockford's industry leading technology capabilities:

MOSFET Amplifiers

The Metal Oxide Semiconductor Field Effect Transistor (MOSFET) has definite advantages over traditional "bi-polar" devices. It provides extremely fast switching speed. The ultrawide bandwidth delivers effortless performance and because the technology is very rugged, it can pass huge bolts of current into a loudspeaker. And, it has "soft saturation," much like the best feature of tubes.

Trans-nova

Rockford's patented Trans-nova technology provides voltage and current gain at the output state (power gain), unlike other amplifier designs that use "buffers" following voltage gain stages, killing current gain and requiring more parts that result in more noise and distortion. The simple nature of Trans-nova technology provides transparent, dynamic and 3-dimensional sound using the fewest components possible.

Diamond -- Dynamically Invariant Amplifier Operational Nodal Drive

Rockford's Diamond circuitry provides the linearity of a class A operation, the ultimate in pure amplification accuracy, with the efficiency of class AB, which minimizes heat and maximizes efficiency. Diamond also provides up to 14dB additional headroom in the amplifier front end to deliver wider dynamic range and pure sound quality.

High-Clarity Speakers

Rockford optimizes its speaker systems for low distortion and pure sound. It does this by matching system components, creating linear suspensions with damping limits, controlling sound waves directivity and using motor structures that control excursion.

DSP/Speaker and Sound Field Correction

It also utilizes advanced DSP (digital signal processor) technology to correct system speakers and to optimize them to the listening environment including: 1) total correction of frequency and phase anomalies to provide a broad, accurate soundstage and, 2) high resolution of distortion characteristics similar to quality electronic components.
