EMS-159

EM Acoustics set out to create the finest two-way medium format loudspeakers possible, and the result is the EMS-159. Utilising our latest passive crossover topologies, and the utmost in drive unit technology, this loudspeaker is completely passive yet outperforms many bi-amplified or processed designs. The EMS-159 is ideal for front-of-house duty for medium to large venues, or as a powerful fill loudspeaker for larger systems.
  • True passive design – no corrective DSP required
  • Wide and narrow dispersion variants in identical enclosure footprints
  • 35mm polemount
  • Rotatable 90° x 60° waveguide
  • Flexible rigging and mounting options
  • Impact and weather resistant black or white textured finish as standard
  • RAL colour and enhanced weather protection options

The EMS-159 is a two-way passive loudspeaker, using a 4” (102mm) voice coil 15” (381mm) neodymium low frequency transducer. This low frequency drive unit is coupled via the internal passive crossover network to a 4” (102mm) diaphragm, 1.4” (36mm) exit neodymium high frequency transducer. This drive unit loads onto a constant-coverage horn, which yields not only consistent response throughout its operating band across the whole coverage pattern but also strong attenuation outside of this pattern. The result is a loudspeaker with extremely consistent and predictable coverage, as well as stunning sonic detail – and all with the ease of use that passive crossover technology brings.

The drive units are housed within a compact, vented enclosure. The robust enclosure is constructed from premium 15mm (5/8”) multi-laminate Birch plywood, and is heavily braced to minimise panel reflection. Incorporated within the enclosure are multi-use rigging plates, which allow suspension of the loudspeaker swiftly and safely in a variety of ways. The primary rigging system utilises keyhole plates and quick-release pins to allow attachment or removal of hardware in seconds.

Each plate (top and bottom of the enclosure) provides four exposed-thread M10 rigging points as well as the keyhole mounts, and an M8 safety/pull-back point is provided on the rear of the enclosure. A 35mm polemount socket is provided discreetly on the underside for stand mounting.

The enclosure also includes two flush bar handles, and a pair of Neutrik® speakON™ connectors for input and enclosure link. Lastly, a tough hex-punched stainless steel grille backed with acoustically transparent fabric protects the drive units from damage. The grille can be quickly removed to rotate the HF waveguide if required, and the orientation of the waveguide can be determined without removing the grille. The enclosure is finished in impact and weather resistant black or white textured polyurethane as standard, though RAL colour matching and enhanced weather-protected outdoor options are available.

The EMS-159 requires a single amplifier channel, and the use of external DSP is recommended for system protection with high pass filters and limiters – as such it is recommended to be used with EM Acoustics’ range of Advanced System Amplifiers. It is however possible to use other DSP-enabled amplifiers, or conventional amplifiers with external DSP. Suitable DSP settings are provided on the EM Acoustics website. The EMS-159 requires a single amplifier channel capable of delivering 1000-1500W RMS into an 8-ohm load.
