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.

REMOVE AND DISCARD 23 #8 X 5/8 LG PHILLIPS HEAD SHEET METAL SCREWS

10X GRILL FOAM RETAINERS (DO NOT REMOVE)

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.
