Electro-Voice Xi-1183A/64F

The Electro-Voice® Xi-1183A/64F is a full-bandwidth, threeway, triamp system is designed for medium- to long-throw applications. The orientation of LF section and the midbass horn create a two-element line array that extends vertical pattern control to below 350 Hz. Using VBS (Vertical Beam Shaping) technology this benefit can be increased by another 20° to 40° of pattern control above 300 Hz. VBS uses filters to overlap the LF section bandpass with midbass bandpass. By carefully phase matching the acoustic response in the overlap region the vertical pattern control is dramatically improved as seen in the graphs on Page 2. Frequency response on-axis is unaffected, while gain before feedback is increased by 10 to 15 dB for microphones located under the loudspeaker. Its high-frequency horn/driver section is rotatable to provide proper coverage for vertical or horizontal system installations. The low-frequency section is powered by an 18-inch driver (EVX-180B) in a slot-loaded, closed box configuration suitable for moderately high sound pressure levels. When very high levels are desired we suggest augmenting with the Xi-1191A. For maximum lowfrequency performance, combine in a four-way configuration. The ND12A 12-inch, application-specific mid-bass driver features RMD™ and a 60° x 40° horn. The ND6-16 highfrequency driver/horn combination is fully “shrouded” to preserve midbass wave-front detail.
