3. If you plan to use grilles or panels in front of the loudspeaker, en- s u r e
that sufficient space is available for the path of the loudspeaker cone .
Should the distance not be sufficient, the cone could vibrate
against the grille or panel thus damaging the loudspeaker.
Installing the Tweeters (only NCS 525/700)
The tweeters can be flush- and surface-mounted. Consider that repeated
opening and closing of the car door can result in loosening of the tweeter
fastening devices, when the loudspeaker is mounted in the door panel.
1. Flush mounting: Use the enclosed drilling template to cut a suit-
able hole. Lay the leading connector cable and mount the parts as
The specialty of the ETON mounting cabinet is that the tweeter ele-
ment can be turned and swiveled to achieve the optimum hearing
path to your sitting position. See figure 3.
Disassambly: To remove the tweeter element from the mounting
cabinet turn the element to its middle position and place two round
metal rods with a diameter of 1,0 mm to the limit in both openings
right and left of the tweeter element. By swiveling of the tweeter you
can now move it upwards and remove it.
2. Surface mounting: Drill two holes for the fastening screws and one
hole for the leading connector cable using the mounting cabinet as
a guide. Consider the preferred incline of the mounting cabinet.
Mount the parts as shown in figure 4.
2. Use the enclosed drilling template to cut a suitable hole in the trim
panel and, if necessary, in the sheet metal behind. Drill holes for the
fastening screws. Mount the parts as shown in figure 1.
Attention: If sheet metal must be cut or removed contact your
authorized car dealer for professional advice. By damage to sup-
porting body structures the safety certificate may be withdrawn.
Caution: Use care when removing interior trim panels. Car manu-
facturers use a variety of fastening devices that can be damaged in the
disassembly process.
