Bose Professional MB24 overview

  • 1Description

The black MB24 from Bose is a modular bass loudspeaker designed to provide bass augmentation for Bose LT arrays and other subwoofer applications. The Baltic birch enclosure features dual 12" high-excursion woofers with 4" voice-coils and a discrete power handling of 800W RMS (3200W peak). The subwoofer offers a frequency response of 40 to 280 Hz and features a front-loaded transmission line design that provides a peak-free extended low-frequency, reducing port turbulence distortion.

  • Low-frequency reinforcement for Bose LT arrays and other subwoofer applications that require 40 to 280 Hz bass response
  • Front-loaded tapered transmission line design provides peak-free extended low-frequency response and reduces port turbulence distortion
  • 2 x 12.0" high-excursion woofers with 4.0" voice-coils and 800W 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
