Loudspeaker
Loudspeaker Description
The built-in loudspeaker is mounted on the top cover. A grill cloth covering the sound holes keeps dust and
debris from falling into the speaker cone. The loudspeaker is equipped with a magnetic shield to avoid unwanted
interaction with nearby circuits.
Loudspeaker Installation Procedure
Locate the top cover and check the inside for any masking tape still covering screw holes. If found, peel it
off.
Mount the chassis stiffening bracket on the underside of the cover as shown in Figure 77. Do not use
washers.
Figure 77. Attaching Chassis Stiffener to Top Cover.
Trim the grill cloth to cover the speaker grill openings and overlap the four holes for the loudspeaker
mounting screws. Mark and cut four holes in the grill cloth for screws to pass through the cloth. The grill cloth
is shown as it must fit after the speaker is mounted in Figure 78. Normally, the stiffener will remain attached to
the K3 when you remove the top cover. If you install the KPA3 100-watt amplifier, the stiffener will be attached
to the KPA3 shield and cannot be removed with the cover (see Figure 82 on page 58). The grill cloth must be
trimmed as shown so it cannot become trapped between the chassis stiffener and the top cover when the cover is
removed and replaced.
CAUTION!
Failing to install the fiber washers as shown in the next step or over-tightening the screws so
that the speaker mounting flanges are distorted may damage the speaker, causing distorted,
fuzzy sound.
