The MSE-156 is a compact, versatile, passive loudspeaker product designed for a wide variety professional sound reinforcement applications. It features a high-power 15” (381mm) neodymium LF drive unit in a reflex enclosure, and a 4” diaphragm, 1.4” (36mm) exit neodymium high frequency compression drive unit coupled to a 60° x 40° rotatable waveguide. These components are matched by an internal passive crossover network for unprecedented sonic quality from a completely passive enclosure. Sonic performance and character is incredibly consistent, allowing easy mixing of the different products within a system.

Due to its discreet size and appearance, the MSE-156 can be used in a wide variety of professional audio applications ranging from corporate and theatre use up to medium scale front-of-house or in-fill/out-fill for
much larger systems. The primary intention for the MSE-159 and MSE-156 were primary loudspeakers for theatrical sound reinforcement.

As with all EM Acoustics full-range products, no active controller or programmed EQ is required for correct operation. For demanding applications, a 50Hz, 24dB/octave high pass filter is recommended to increase drive unit headroom however this is not essential for normal operation.
