The VQ MB is a high powered low/mid frequency module that replicates the low frequency section of the VQ 60 & VQ 100 full range loudspeakers and can be flown or ground stacked to provide improved LF pattern control with full range or mid/high systems in the VQ series. Two (12”) low frequency transducers offer high power handling and low power compression for high continuous SPL capability. A newly designed LF loading design provides the highest possible sensitivity for low/mid frequency output (105 dB/w). The VQ MB is principally intended for use with the VQ 60, VQ 100, VQ MH & VQ DF full range systems and can be used construct arrays with extended low frequency pattern control. By fixing a VQ MB at the opposing end of a VQ full range loudspeaker we can effectively extend pattern control to below the cutoff point of the Mid/High PSW waveguide.
