Overview
15” Horn-Loaded Full-Range Loudspeaker System
PD544 is a Precision Directivity™ loudspeaker designed for applications requiring high output capability with excellent pattern control. PD544 can be utilized in music or speech systems where frequency extension to 80 Hz is adequate or combined with subwoofers to create extended bandwidth fullrange systems.
Features
- 380 mm (15”) horn-loaded low-frequency driver
- Large PT™ Progressive Transition™ waveguidesprovide broad band 40° x 40° pattern control, low distortion at high SPL levels and smooth frequency response
- Rotatable waveguide allows for either horizontal or vertical cabinet orientation
- Sophisticated, steep-slope passive crossover network with switchable bi-amp/passive crossover modes
- Sports Facilities
- Performance spaces
- Auditoriums
- Worship facilities
