EXPLODED VIEW
TO SERVICE THE K2 S9800The crossover network, after removal of the (6) faceplate screws,
should extract far enough out of the cabinet for service without wire or
driver removal.
Access to 9V bias batteries -“ metal plate removed by two thumbscrews
on the network faceplate.
Replacement or service of the high-frequency drivers requires access
through the woofer opening, following these steps:
NOTE: IT IS RECOMMENDED TWO PERSONS BE INVOLVED IN
K2S9800 DISASSEMBLY
1) Lay the loudspeaker down, on its back (drivers facing up), on a
padded surface.
2) Remove the grille.
3) Remove the (8) Phillips woofer screws.
4) The woofer is best extracted by inserting two 1/4 x 20 (3" or longer)
threaded machine screws into opposite sides of the two threaded
woofer screw openings. Caution: Only two of the holes are threaded;
they should be the top and bottom holes in the woofer frame. Threadthe bolts into the openings by hand, then pull upwards, lifting the woofer
from the counterbore. Then, while one person supports the woofer,
another can remove both connecting wires from the terminals. Set the
woofer aside.
5) Inside the cabinet, at the bottom of the HF horn, are the three
mounting screws; remove them.
6) The HF horn can now be removed from the cabinet by reaching in
and pushing the assembly out; remove both connecting wires from the
terminals. Set the HF assembly/horn aside.
7) The (10) screws holding the top cap assembly are now exposed;
remove them.
8) Lift the top cap assembly with UHF assembly off the cabinet.
NOTE:
a) When replacing the HF horn, to assist the (3) screw holes in lining
up properly, one person may have to depress the gasket by pressing
the horn assembly down into the cabinet, while the other replaces
the screws.
b) Remember to observe correct polarity when reattaching all driver wires.
