remove in a container to prevent loss. In order to ensure the safe operation, all hardware must be properly
replaced.
Disassembly:
1. Disconnect the cable leading to the High-Frequency Driver. Rotate the collar on the connector at the bottom of
the HF Driver and pull the connector away from the driver.
2. Loosen the four nuts located on the inside of the driver-mounting flange of the Waveguide assembly. Remove
the nuts and accompanying washers.
3. Using both hands, lift the driver off of the Waveguide. Avoid dropping the Driver as this can cause serious
damage and render it unrepairable.
Diaphragm replacement can be accomplished with a Phillips screwdriver. Due to the powerful magnetic field
around the voice coil, special care must be taken to not damage the new diaphragm as the magnetic field pulls
on any steel tools. Diaphragm replacement is best done in a clean environment by technicians experienced with
this procedure. Simply replacing the entire compression driver with a new spare unit allows the damaged
diaphragm to be carefully inspected and repaired in a controlled work environment.
HF Driver Replacement:
1. Place the 2451JSLJ HF Driver on the rear flange of the Waveguide with the connector pointing in the direction
of the Magazine, allowing the four studs to pass through the holes in the flange.
2. Attach the four nuts/washers and tighten. Avoid over-tightening as this may damage the driver or the flange.
3. Re-connect the High Frequency Driver. Pay special attention to the orientation of the connector. The key
should face the rear of the spaceframe. Do not force the connector, it should slide in easily.
Subwoofer Replacement:
You will need a #2 Phillips screwdriver and an Allen driver. Be certain to place all the hardware that you remove
in a container to prevent loss. In order to ensure the safe operation of the unit, all hardware must be properly
replaced at the end of this procedure.
1. Lay the unit on its back. Due to the weight, it is advised that two people perform this operation.
2. Remove the grille. Loosen all 18 machine screws holding the grille in place. Do not remove them from the
grille. The rubber spacers on the inside of the grille should remain on the screws. Once all the screws are
disengaged, lift the grille and place it on a flat surface.
3. Using the screwdriver, remove the (8) 1/4-20 machine screws holding the driver. Be careful not to puncture the
cone with the screwdriver - this is a common occurrence.
