Rockford Fosgate RFA-614, RFA-514, RFA-414 manual Zobel Network

◆Zobel Network

The Zobel network compensate for the impedance rise presented by the driver (speaker). The network flattens out the gradual impedance rise produced by the voice coil which typically results in high frequency rolloff. The Zobel Network compensates for this natural rolloff which allows the driver to produce a more linear response up to the tweeter crossover point.

THE RESULT: Compensates for natural high frequency rolloff of midrange.

◆Adjustable Tweeter Level Matching

The RFA-142x utilizes a series power resistor for tweeter level matching. The factory set tweeter output level is –0dB, however, can be reduced –3dB to create a smoother transition between the midrange and tweeter. The ability to level match allows the system to be custom “tuned” for a particular listener or setup.

THE RESULT: Allows custom setup of tweeter output level.
