Description
Compact 1 x 12" (305 mm) configuration designed to provide bass augmentation for Bose® LT arrays and other subwoofer applications. Allows minimal-height arrays when used with LT mid/high loudspeakers. MB12 for indoor applications only.
Features:
- Low-frequency reinforcement for Bose® LT arrays and other subwoofer applications that require 40 - 280 Hz bass response
- Front-loaded tapered transmission line design provides peak-free extended low-frequency response, and reduces port turbulence distortion
- 1 x 12" (305 mm) high-excursion woofer with 4" (102 mm) voice-coil and 400 W long-term power rating provides high SPL with fast transient response
- Compact enclosure optimized for bass-array applications when cardioid or other directional-bass configurations are required for reverberant spaces
Applications:
- Stadiums
- Arenas
- Houses of worship
- Auditoriums
- Performing arts venues
- Outdoor event venues
