The Bose® Panaray® LT Series III Loudspeakers are designed to provide quality sound in venues where speaker-to-listener distance, room reverberation time, ambient noise and high SPL requirements are key factors. Typical installations include performing arts facilities, theaters, auditoriums, houses of worship, stadiums and arenas.
The Panaray LT Series III loudspeakers are a direct replacement for the Panaray LT Series II loudspeaker in indoor spaces. The Panaray LT Series III loudspeaker does not meet the requirements for permanent outdoor installation.
The Panaray LT Series III loudspeakers utilize a high frequency compression driver and two or more V2 assemblies for midrange. The MB24 bass module contains two 12 inch bass drivers. The MB12 bass module contains one 12 bass driver.
The Panaray LT Series III loudspeakers come standard with a perforated metal grille and are available in both black and white versions.
1.This part is not normally available from Customer Service. Approval from the Field Service Manager is required before ordering.
2.The individual parts located on the PCBs are listed in the Electrical Part List.
3. This part is critical for safety purposes. Failure to use a substitute replacement with the same safety characteristics as the recommended replacement part might create shock, fire
and/or other hazards.
4.This part is referenced for informational purposes only. It is not stocked as a repair part. Refer to the next higher assembly for a replacement part.
