PRODUCT DESCRIPTION

The Bose® Panaray® LT Weather Resistant (WR) 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 L T WR loudspeakers are a direct replacement for the Panaray LT Series III loudspeaker. They are designed to be used in both indoor and under cover or out door environments. The Panaray LT WR loudspeaker does not meet the requirements for permanent outdoor installation.

The Panaray LT WR 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 WR loudspeakers come standard with a perforated metal grille and are available in both black and white versions.
