In 1973, Jim Fosgate made a startling discovery while working in his garage in Arizona, USA. Mr. Fosgate realized that music and the human ear have different audio properties. The human ear didn’t have the same sonic “curve” or signature, which made lower frequencies sound different at low volumes than the actual music. Mr. Fosgate invented a solution- the patented Punch EQ, which adds a Bass Boost of up to +18dB at 45HZ and/or +12dB at 20kHz, a Treble Boost enabling better sound reproduction in the ear (a hinge filter active from 1kHz to 20kHz).
In other words, that’s a lot of control! Your entire driving environment - car windows, road noise and your annoying life mate that never stops yappin'… all benefit from the musical energy that Punch EQ injects back into the system. The sound of THE PUNCH gave Mr. Fosgate’s first customers the impact that their music needed. Now… that same PUNCH is the sound of Rockford Fosgate® and you can hear it in everything we make.
