The EMS-121 has been designed to function in any situation ranging from 'stand alone' to small clusters with low frequency support i.e. for theatre/AV work. Careful driver design and enclosure venting provides a useful amount of low frequency information without compromising the fidelity of the sound produced and resorting to a one note 'boom-box' characteristic.

The EMS-121 is a passive enclosure and therefore does not require a controller. At EM Acoustics we believe it is possible to build passive loudspeakers without compromising sonic quality. Extensive crossover R&D has led to an enclosure that is remarkably free from time-smearing often associated with passive enclosures.

The CNC-machined enclosure is manufactured from 15mm multi-laminate Finnish birch ply, and contains a high-power 12" vented LF driver and a 1" exit compression driver. The EMS-121 is available in 60°H x 40°V or 90°H x 40°V (EMS-121w) HF dispersion.

Standard features and rigging

Include a 35mm pole mount, ten M10 rigging points for suspension (either via forged shoulder eyebolts or using the optional FC-121 horizontal or vertical flying cradles), flush handles and dual Neutrik Speakon™ NL4 connectors. The enclosure is finished in black semi-matt textured paint (colours optional) and the front is protected by an acoustic foam/expanded steel mesh grille.
