FACTS ABOUT DLS T20 TWEETER
FLUSH MOUNTING:
Drill a hole with a diameter of 51 mm. Put the two metal wings (6)
through the two tracks (7) in the center of the cup, just as the picture
shows, and attach them with the M4 screw and nut (8) through the
center hole. The cup is attached to the door side when the metal wings
are pressed to the back side of the door.
Put the tweeter element into the cup with the cable going out through
the bottom hole (9). Then attach the element by putting the ring (5) into
the space between the cup and the element.
SURFACE MOUNTING:
MOUNTING:
T20 can be mounted on the dashboard with the angled cup (2) or the
plain mounting plate (3), or recessed in a doorside with the flush cup (4).
For straight surface mounting use only the
plain mounting plate (3). Fasten with two
screws.
For angled surface mounting use the plain
mounting plate (3) together with the angled
cup (2). The plate is attached to the cup
with two small screws. The tweeter ele-
ment (1) is attached to the cup by fitting
the three wings into the tracks of the cup
and then twist it clockwise.
