2. Overview
KF850z Kit installation requires the technician to remove and replace all transducer components. The HF
horn assembly is accessed from the front and the 15” woofer, 10” mid range, and electrical assembly from
the back.
To do this the enclosure will first be rested on its back, the grille
removed, and the HF horn assembly disconnected, removed, and dis-
assembled. Its rear bracket will be re-installed into the new KF850z
HF horn assembly, which will then be installed into the enclosure.
After this is complete the enclosure should be repositioned onto its
front, and the 2 access lids, polyfill, input and crossover removed, the
new crossover installed, and its leads routed to the appropriate cham-
bers. Then the new 15” woofer and the new mid assembly will be
installed. The old polyfill should be restapled into both chambers and
the new electrical assembly installed.
Finally the enclosure will be stood upright, HF leads connected, test-
ed for continuity, and access lids and grille reinstalled.
3. Instructions: Tip the enclosure on its back and remove the 23
Phillips head screws that mount the grille to the enclosure.
