The ESB 3.28 tweeter can be installed with different solution, this depend of car
type, factory location and tweeter position or listening angle. First solution is to
use the back thread hole and with M4x3 screw; use this for fix in an existing panel
or use a plastic or steel bracket for fix it. Use flat head screws type. Screw it by hand
with limited torque when close. Note: Never insert any screw over 4 mm inside back
thread of tweeter motor, this can crack the magnet and damage the tweeter.
Other mounting system can be with multi holes bracket. Bracket can be screwed
on car factory location by side holes. There are three couple with different lengths
(77, 97 and 117 mm). Cut the excess if needed. For flush mounting cut the six
“bridges” that join the central ring to the side bracket of the adapter. Insert the
tweeter from upper side and then push it inside the ring.

Basic mounting system is to use the four Allen screws and fix the 3.28 by the 4
mounting holes from face-plate. Similar mounting and fixing solution is to use the
back screw for fix the metal spring.
The tweeter can be mounted to a surface via the mounting cup. Choose the angle
and position you prefer. Drill holes for cables and screws. After this fasten the cup
with two screws. Be safe with the cables, they must be free when the tweeter is
inserted into the cup.
The 3.28 tweeter use a pair of soft and super flexible cable, all are black, but on
terminals end there are the polarity identification by red and black insulation tubes.
