Description
The EMS-81 is the smallest enclosure in the EMS series. Multi-purpose is the design intent - consequently the EMS-81 is ideal for theatres, corporate & A/V, nightclub or café infills as well as small-scale front-of-house. The quasi-trapezoid enclosure means it can be used as a compact floor monitor for ultimate flexibility. “Opera buffs and the musicians themselves often hate the idea of sound reinforcement, so we must be doing something right when they come out with smiles on their faces, singing the tunes happily to themselves...†Ian McDonald - BBC Consultant and owner of Ivysound  Simple and elegantThe EMS-81 is a passive enclosure and 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 of the time-smearing often associated with passive enclosures. ConstructionThe CNC-machined enclosure is manufactured from 15mm (5/8") multi-laminate Finnish birch ply, and contains a high-power 8" vented LF driver and a 1" exit compression driver on a rotatable 90H x 60V horn. Standard features and riggingInclude a 35mm pole mount, ten M10 rigging points for suspension (either via forged shoulder eyebolts or using the optional FC-81 horizontal or vertical flying cradles), a flush handle 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. The enclosure is also available as the EMS-81i installation version (fitted with a single NL4MP connector and a 4-way barrier strip) and the EMS-81v 100V line version. |
