Compact two-way passive loudspeaker


Compact two-way passive reflex-loaded loudspeaker

Asymmetrical multi-angled cabinet for FOH or stage monitor use

Signature EM Acoustics passive crossover for unprecedented frequency and phase response

6.5" neodymium LF drive unit, 1" exit neodymium HF transducer

The EMS-61 is a compact two-way multipurpose loudspeaker intended for a variety of applications – either as a stand-alone product, or else with the incorporation of EMS-112 or other EMS Series subwoofers to make a truly fullrange system.

  • Rotatable 90° x 60° constant directivity waveguide
  • Premium 12mm multi-laminate birch plywood enclosure
  • Black or white textured paint finish
  • Optional weather protection or RAL custom colours
  • Multiple threaded rigging points compatible with OmniMount and Powerdrive brackets
  • Pole mount socket
  • Hex punched steel grille backed with acoustically transparent black foam

The EMS-61 is completely passive, yet outperforms many bi-amplified or DSP-processed designs. The enclosure contains an 6.5” (165mm) neodymium LF drive unit, linked via the internal passive crossover network to a 1.7” (44mm) diaphragm, 1” (25mm) exit HF compression drive unit. The HF drive unit is coupled to a constant-directivity waveguide, which produces a 90° x 60° dispersion pattern which can be easily rotated if required.

The multi-angle enclosure along with the rotatable HF waveguide allows use in both horizontal and vertical orientations, as well as use as a compact stage monitor. The robust enclosure is constructed from premium multi-laminate Birch plywood and is finished in impact resistant textured paint. Two NL4 connections are provided for input and enclosure link. The front of the loudspeaker is protected by a rigid steel grille backed by acoustically transparent foam. Various threaded fixings are provided in the enclosure for optional rigging hardware. RAL colour matching and weather protection options are also available if required.

The EMS-61 requires a single amplifier channel, and should be used with professional power amplifiers capable of delivering 300-500W RMS into an 8-ohm load. For optimum results, the EM Acoustics DQ Series Advanced System Amplifiers, or the AQ Series power amplifiers in conjunction with the DSC48 system controller (for loudspeaker protection) should be used.
