Rockford Fosgate RFA-414, RFA-514, RFA-614 I

•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

– 9 –

® ®

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 415⁄16"

• For the RFA-64, cut a 527⁄32"" (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.
