-Inch Super Horn Tweeter features a high quality
ceramic bimorph driver element. This ceramic driver replaces the tradi-
tional voice coil and magnetic structure, completely eliminating the
most common causes of magnetic tweeter failure — distortion due to
mechanical interference (such as dirt on the voice coil) and magnetic
interference from the voice coil.
The tweeter requires no crossover network (crossover is optional), no
specific baffling, and can be used on most 4-, 8-, and 16-ohm speak-
ers.
WIRING
Make sure the audio system is off before you connect any wires, and
leave enough slack in the wires so they can easily reach the terminals.
Connect speaker wire from one of your audio system’s positive out-
puts to one of the tweeter’s positive (+) terminals.
Connect speaker wire from your audio system’s matching negative
output to one of the tweeter’s negative (–) terminals.
Caution: Be sure all wiring is clear of sharp edges.
MOUNTING
Before mounting your tweeter, wire it to your audio system and test the
connections. Depending on the location you select, you might not be
able to reach the tweeter’s terminals after mounting.
You need four

-inch screws (not supplied) to mount the tweeter in-
side an enclosure. If necessary, cut a 3-inch hole in the enclosure to
accommodate the tweeter.
Mount the tweeter from the outside, so its front edge is flush with the
front of the mounting surface for proper sound dispersion.
Follow these steps to mount the tweeter.
1. Use the tweeter’s horn as a template to mark the locations for the
mounting holes.
2. Drill four

-inch (3 mm) holes in the mounting locations.
3. Secure the tweeter to the mounting location with the screws.
