Bullet Horn Tweeter
Your Optimus Bullet Horn Tweeter features a high quality
piezo ceramic disc drive bimorph driver element. This ce-
ramic driver replaces the traditional voice coil and mag-
netic structure, completely eliminating the most common
causes of magnetic tweeter failure — distortion due to
mechanical interference (such as dirt on the voice coil)
and the voice coil interfering with the magnetic structure.
The tweeter requires no crossover network (crossover is
optional) and no specific baffling, and can be used on
most 4-, 8-, and 16- ohm speakers.
WIRING
Wire the tweeter to your audio system, then test the con-
nections.
Connect speaker wire from one of your audio system’s
positive outputs to the tweeter’s positive (+) terminal.
Connect speaker wire from your audio system’s matching
negative output to the tweeter’s unmarked negative (–)
terminal.
Cautions:
• Be sure all wiring is fully protected from sharp edges.
• Be sure the audio system is off when connecting any
wires.
• Leave enough slack in the wires so they can reach
the terminals easily.
MOUNTING
If you decide to mount the tweeter inside an enclosure,
temporarily disconnect the tweeter while you mount it.
If necessary, cut a hole in the enclosure 3

flush with the front of the mounting surface for proper
sound dispersion.
