Description
An ultra-compact passive loudspeaker for use where compact size is as important as sonic performance. The EMS-51X (slightly smaller and lighter replacement for EMS-51) is a compact two-way multipurpose loudspeaker intended for a variety of applications – either as a stand-alone product, or else with the incorporation of S-48 or S-12 subwoofers to make a truly fullrange system.
- True passive design – no corrective DSP required
- Sealed enclosure gives gentle 12dB per octave LF roll off
- Flexible rigging and mounting options
- Horizontal yoke included (NB EMS-51X no longer uses vertical yoke)
- Black textured paint as standard
