Adjusting the Directional Sound Lens
Most KICKER Impulse coaxials and the 3-way I6903 have a feature which allows tuning
the high frequency response to your taste. The front of the tweeter incorporates KICKER’s
Directional Sound Lens™ which can be rotated to shape the tweeter’s output. After
mounting and wiring your new speakers, and before securing the grills, you will want to listen to them with the DSL in different positions to determine which angle works best for
you. We suggest you start with the KICKER logo pointed toward the listener’s head, then
rotate until it sounds best to you. Have fun and experiment … with a little work you’ll get
greatly superior imaging can is possible with conventional coaxial speakers.
INSTALLATION INSTRUCTIONS
Your KICKER drivers are specifically designed for mounting in free-air applications. While
the speakers don’t need a sealed box to work in, for optimum performance it is important
to isolate the sound coming off the front of the driver from the sound radiating from the
back of the driver. This isolation is usually accomplished by using the correct size driver in a
factory speaker location.
Mounting
If custom door mounting locations are desired for your drivers, be careful to avoid
interference from window and door lock mechanisms. The first step is to find a location on
the door panel that will accept the size of speaker chosen. Then remove the door panel
from the door, and check for the operation of the window all the way up and down.
If metal must be cut to mount the speakers, try to avoid structural metal and braces.
On models with grills included, mount as indicated in the following diagram. There is a supply of butyl rubber adhesive included to help hold the grill on the ring.
If factory door speaker wiring is not available to tie into, it is necessary to run the supplied wire through the door jamb. This wire should be kept away from sharp edges and the
possibility of getting pinched. An existing boot in the door jamb is the ideal place to run
the wires, but sometimes this does not exist or is inaccessible. Drilling holes to run wires
through is very tricky, and caution must be exercised not to drill into other wiring or mechanisms. Any time a wire is run through a bare hole, it is necessary to insert a rubber grommet first to protect the wire.
