Carefully begin to remove the entire horn assembly (with the high and mid frequency drivers still attached). A flat head screwdriver may aid in loosening the horn assembly from the cabinet if it is sticking. Caution: The horn weighs about 10 pounds, and the weight is not evenly distributed.

The high frequency driver should easily lift right off of the horn assembly. Holding down the horn assembly with one hand while lifting up on the driver with the other hand may help.

Turning the high frequency driver over reveals the cover plate which needs to be removed using the phillips head screwdriver. Replace with the new driver (part #0013925) and follow the same steps as above, but backwards 11 to 1. Power up the SA1232z and the new driver should now be pumping out those highs again. Fantastic, you just replaced a high frequency driver!

Diaphragm replacement:
1
At the present time (December 2006), diaphragms are not currently available, so you will have to replace the complete driver following the previous section (pages 9-12). Follow steps 1-6 of the high frequency driver replacement instructions, as the horn assembly will need to be removed in order to access the diaphragm.

The covers may be worked loose by wedging a flat head screwdriver in between the cabinet and the cover, as well as the amplifier assembly and cover. Make sure to get around the entire cover plate in order to be able to remove them.
