PRODUCT DESCRIPTION
The Bose® Panaray® L T 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.
