Section 9. - SYSTEM MAINTENANCE AND REPAIR TIPS
The HLA system is designed to provide many years of professional service. The only wood used in the
entire system will be found in the replaceable “skid plates”. The wooden skid plates can be replaced if needed.
System owners can fabricate their own, or order JBL part number 380-10000-02 (Model 4895 three-way) or 380-
20000-02 (Model 4897 subwoofer).
For prolonged outdoor exposure, a protective housing should be placed over the HLA clusters. In
traveling systems, care should be taken to prevent damage to the aluminum Spaceframes. If HLA speakers sustain
damage to the Spaceframe, it will reduce their structural integrity. Routine inspection for frame dents and
cracked welds should be a regular part of assembling and striking arrays. If a 4897 subwoofer sustains damage to
its enclosure that results in a puncture in the resin coating, exposing the fiber material beneath, it should be
repaired. Water or water vapor absorbed into the structural core may degrade the enclosure.
Grille Removal and Replacement
The removal and replacement of a perforated metal grille for the HLA 4895 or 4897 will require use of
proper tools and paying careful attention to detail. It may be helpful to perform the operation as a practice
procedure in the shop upon first receiving your HLA units.
