IBO'S Proprietary Weatherproof Construction process

  Weatherproof input connector plate    


Marine grade plywood manufactured using waterproof adhesives

Specially formulated waterproof epoxy adhesives and fillers used throughout cabinet construction

Stainless steel or structural aluminum hardware throughout,including high strength stainless steelthreaded fasteners

Fiberglass resin coating on all exterior cabinet surfaces

Waterproof epoxy coating on all interior cabinet surfaces

Three-layer weatherproof grill including a powder-coated perforated stainless steel outer grill,an ozone-resistant,fungus proof open cell foam middle grill as a dust and water barrier,and an acoustically transparent stainless steel mesh water barrier with 10000pores to the inch

All paper cone transducers treated with special IBO weatherproofing process

waterproof high temperature glues used in assembly of passive internal networks



The standard input configuration for WP systems consists of a barrier strip mounted to a phenolic panel which is recessed into the rear of the enclosure for extreme conditions,this panel can be covered by a removable 1/8-in thick aluminum plate the plate is attached to the enclosure stalnles steel machine screws A weather proof gasket between plate and enclosure insures that the seal is impervious to moisture the plate holds water proof gland-seal nuts through which the connecting cable is routed.
