HF driver or diaphragm replacing procedure
1. To install a full HF driver:
a. Install the new driver on the heat dissipation plate.
b. Screw in both Torx
c. Install the HF assembly on the LF loudspeaker and screw in both hex screws through the HF heat
dissipation plate (5 N.m/45 in.lb
To install a diaphragm only:
a. Ensure that the voice coil gap on the driver is free from any particles. If necessary, clean out the gap
by using 2-sided tape.
b. Install the new diaphragm in the gap, install the back cover.
c. Screw in the 4 hex screws on the back cover (3 N.m/27 in.lb
between screws at every moment while screwing in so as to properly center the diaphragm.
d. Apply a low level LF sine wave (for example: 1 volt at 440 Hz) to ensure that the diaphragm is
properly centered in the gap (the sound should remain pure and free of any unwanted noise). If not,
slightly unscrew, center, screw, and make another test.
2. Connect both cables to both new diaphragm terminal posts: connect the blue cable to the red terminal
post and the white cable to the black terminal post (push on the spring-loaded terminal post, slide the
cable in, and release the terminal post).
3. Install the loudspeaker assembly in the enclosure and screw in the 4 hex screws with flat washers
and mounting brackets: into each hex screw insert a flat washer and then a mounting bracket (following this
sequence) and screw in the assembly to one of the four locations (5 N.m/45 in.lb
