Rockford Fosgate RFA-514, RFA-414, RFA-614 manual Installation, Mounting the Midrange

Sound radiated from a “point source” has the most optimum stereo imaging because the separation of the acoustical centers between the midrange and tweeter for each channel is at the optimum. Figure 2-A describes a horizontal speaker alignment. In a closed environ- ment such as an automobile, horizontal speaker alignment can cause severe amplitude and phase differences which will degrade not only the imaging, but also the frequency response. This is due to the path length differences between the midrange and tweeter. Figure 2-B displays a vertical alignment between the midrange and tweeter. With a vertical alignment, the path length difference between the midrange and tweeter are reduced to a minimum. The result is a negligible difference in path lengths between the midrange and tweeter regardless of the proximity of the listener to the speakers. Mounting the speaker with minimum path length differ- ence will ensure the best staging an imaging possible from your audio system.

INSTALLATION

Mounting the Midrange

I

N S T A L L A T I O N

1.Cut the proper size hole for the midrange/woofer.

For the RFA-44, cut a 4" (101.6mm) diameter hole

For the RFA-54, cut a 41516"

For the RFA-64, cut a 52732"" (148.4mm) diameter hole

2.Place the mounting ring over the mounting hole and mark the location of the screw mounting holes.

3.Remove the ring. Drill the holes for the screws using a 1/8" drill bit.

4.Route the wire through the hole.

5.Install the screw clips (Tinnerman clips) over the screw holes. Place the mounting ring over the hole.

6.Attach the wires and be sure to observe the proper speaker polarity.

7.Place the speaker into the hole and screw the speaker into place.

Be careful not to bend the speaker frame during this step.

8.Press the speaker grille into the mounting ring.
