PRODUCT OVERVIEW

EMS-122/EMS-122w fullrange passive loudspeakers
The EMS-122 is a compact, versatile, passive loudspeaker product designed for a wide variety of compact and
discreet sound reinforcement applications. It features a high-power 12" (305mm) 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. The EMS-122w is identical in every respect,
excluding that the rotatable waveguide has a 90° x 60° coverage pattern. Sonic performance and character is
incredibly consistent between the two models, allowing easy mixing of the different products within a system.
Due to its discreet size and appearance, the EMS-122/122w can be used in a wide variety of applications ranging
from corporate and theatre use, to medium scale front of house and floor monitoring duty.
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-122/122w is supplied as standard in black or white, and is fitted with two Neutrik SpeakON NL4MPR
connectors. Custom colours, weather protection and specific connectors can also be supplied if required – please
contact your local EM Acoustics representative for more details.
To rotate the HF waveguide:
1. Remove the front grille as described in the Maintenance section on Page 10 of this manual.
2. Using a 4mm Allen key, remove the eight countersunk bolts retaining the HF waveguide in place.
3. Lift the waveguide up and rotate to the desired position – the label on the waveguide shows the dispersion
orientation.
4. Reinstate the socket-head bolts and retighten. Avoid over-tightening as this may crack the waveguide.
5. Reinstate the grille as described in the Maintenance section on Page 11.
