JBL Professional 888-00025-00 - Enclosure Plate for Control 25 / 25T / 25AV-LS and Control 28 / 28T-60

JBL reference 888-00025-00 is the original Enclosure Plate (back plate) used in several models of the Control Contractor series. This part is part of the rear assembly of the loudspeaker - which integrates elements such as the InvisiBall® system pivot and, depending on the version, the transformer switch - and allows the mechanical closure of the cabinet to be restored while maintaining the factory tightness and aesthetics. It is an OEM spare part documented in the technical parts lists of the Control 25 / 25T / 25AV-LS and Control 28 / 28T-60 , making it ideal for repairs and preventive maintenance in fixed installations.

Main features

• Multi-platform compatibility: Appears in the Control 25 and 25T technical manuals, in the Control 25AV-LS safety version, and in the Control 28/28T-60 .
• InvisiBall® Mount Integration: Designed to work in conjunction with the InvisiBall® pivot ( p/n 888-00026-00 ) and hardware, maintaining system orientation and security.
• Simplified service: fixing by 4 screws (JBL reference associated in the exploded view) and compatibility with accessories close to the panel such as Switch Plug and O-ring (depending on the model).
