The MH121.5 was designed as an even more powerful industry workhorse enclosure. Containing a 1.5-inch high frequency driver, it delivers performance much greater than its physical size and weight. Adamson’s Acoustic Waveguide is employed in the MH121.5 and its integral pole-mount makes installation fast and effective. As with all Adamson enclosures, frequency response, output and beamwidth control are second to none. The MH121.5 packs big power in a small package.
