EM Acoustics EMS-81X - Compact Two-Way Passive Reflex-Loaded Loudspeaker - Black

EM Acoustics EMS-81X

The EM Acoustics EMS-81X is a compact two-way passive reflex-loaded loudspeaker. The ems 81x is designed to be used either as a standalone speaker or incorporated with S-series subwoofers to make a truly full-range system.

Features

• True passive design – no corrective DSP required
• Rotatable 90° x 60° waveguide
• 35mm polemount
• Flexible rigging and mounting options
• Compatible with OmniMount™ and Powerdrive brackets
• Impact and weather resistant black, and textured white finishes as standard
• RAL colour & weather protection options

The enclosure contains an 8” (203mm) 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 a rugged black textured polyurethane or white textured paint as standard, though RAL colour matching and weather-protected outdoor options are available.. Two NL4 connections are provided on the rear for input and enclosure link. The front of the loudspeaker is protected by a rigid steel grille backed with acoustically transparent fabric. A flush handle, 35mm polemount socket and various threaded fixings are provided in the enclosure for optional rigging hardware.

The EMS-81X requires a single amplifier channel, and should be used with professional power amplifiers capable of delivering 400-500W RMS into an 8-ohm load. For optimum results, the EM Acoustics DQ Series Advanced System Amplifiers should be used.
