Electro-Voice X-Array Sound Package en Rumanía

The Xi-2181 is a manifolded, vented-box bass system utilizing two 457-mm (18-in.) woofers. The two woofers face each other in a manifold chamber at the center of the enclosure. This manifolding technique (U.S.Patent Number 4,733,749) increases the acoustic loading, resulting in increased low- frequency efficiency (at slightly above box tuning) and reduced distortion compared to conventional direct-radiating designs. The woofers were designed as part of the Xi-2181 development and represent a step forward in state-of-the-art loudspeaker design in terms of high acoustic output with low distortion and low power compression.
Xi-1183/64 This full-bandwidth, three-way, tri-amp system is designed for medium- to long-throw applications. Its high-frequency horn/driver section is rotatable to provide proper coverage for vertical or horizontal system installations.
