The EMS-126 is a two-way passive loudspeaker, using a 3” voice coil 12” (305mm) neodymium low frequency transducer. This low frequency drive unit is coupled via the internal passive crossover network to a 3” (76mm) 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 rotatable coverage pattern of 60 degrees by 40 degrees, 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 into the top & bottom of the enclosure are a pair of M10 threaded points for attachment of a variety of rigging and flying hardware, and an M8 safety/pull-back point is provided on the rear of the enclosure. A 35mm polemount socket is provided discretely on the underside for stand mounting. The enclosure also includes a flush bar handle on the rear, and a pair of NL4 connectors for input & enclosure link. Lastly, a tough hex-punched 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. The enclosure is finished in black or white textured paint as standard, however RAL colour matching and weather resistant options are also available. The EMS-126 requires a single amplifier channel, and should be used with professional power amplifiers capable of delivering 750- 1000W RMS into an 8-ohm load. For optimal results, either the DQ Series Advanced System Amplifiers, or the AQ or AD Series amplifiers combined with DSC48 processors should be used.
