Bose LT MB12 - Bass Module

Bose LT MB12 - Bass Module

The Bose LT-MB12 is a low-frequency loudspeaker designed to provide bass augmentation for Bose LT arrays and other
subwoofer applications. The compact 1 x 12" (305 mm) configuration allows minimal-height arrays when used with LT mid/high
loudspeakers. Bose Modeler® tools and optional rigging hardware make directional bass arrays easy to design and install using MB12 loudspeakers.

• 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
