Discreet Dual Clamp (DDC™)
Tweeter Mount
Every aspect of the new Tweeter design has been
completely re-engineered to allow for maximum
ease of installation and fitment.This optimized
patent pending design provides concentric
clamping pressure around the perimeter of the
mounting hole.
The “mounting cups” are in fact not “cups” at all,
but rather unobtrusive “clamps” that quickly
and easily mount in a standard 1.75 inch (45mm)
hole saw opening with a single center screw
securing with balanced pressure to both faces
of the mounting surface. From there, the tweeter
simply snaps into place and is secured by a
snap-on trim ring. Removal is easy if needed.
The protective grille on the tweeter is
non-removable and an intergral part of the design.

Crossover Wiring
1.
Use illustration for proper connection.
2.
Be sure to maintain speaker polarity.
3.
Connecting the positive wire to 0dB matches the
amplitude of the tweeter to the mid-range (woofer).
4.
Connecting positive wire to -2dB or -4dB to reduce
the amplitude of the tweeter -2dB or -4dB lower
than the mid-range, (ideal for tweeters located high
in door panels and mid-range low in the kick panel).
