Rockford Fosgate RFA-514 - Manual (Page 8)

◆ 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.
