Bose MB12 III Modular Bass Loudspeaker Speaker ( Black or White )

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
