PRODUCT OVERVIEW
EMS-121X fullrange passive loudspeaker
The EMS-121X is a compact, versatile, fullrange loudspeaker product designed for a wide variety of compact and
discreet sound reinforcement applications.
It features a high-power 12" (305mm) LF drive unit in a reflex
enclosure, and a 1.7" diaphragm, 1" (25mm) exit high frequency compression drive unit. These components are
matched by an internal passive crossover network for unprecedented sonic quality from a completely passive
enclosure.
The EMS-121X is suited to a wide variety of professional audio applications, from corporate and theatre use
through to small-medium scale front of house or nightclub use.
As with all EM Acoustics full-range products, no active controller or programmed EQ is required for correct
operation. For demanding applications, a 65Hz, 24dB/octave high pass filter is recommended to increase drive unit
headroom however this is not essential for normal operation – please see page 7 for further information.
