CEA 2031
Power handling on Rockford Fosgate speakers conform to CEA-2031 industry standards. This means your speaker has the capacity to handle
power under continuous demand, not instantaneous power handling that over time can damage voice coils.
VERIFIED WITH KLIPPEL
To adorn the ‘Verified with Klippel’ mark, the qualifying company’s loudspeaker engineering personnel must be trained and certified by
Klippel prior to using the three separate Klippel systems to design, develop and test. Rockford Fosgate has made the investment in Klippel to
deliver the best possible speakers and subwoofers to their customers.
