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.
The EMS-121X is supplied as standard in black or white, and is fitted with two Neutrik SpeakONTM NL4MPR
connectors. Custom colours, weather protection and specific connectors can also be supplied if required – please
