General Description:
The Electro-Voice® Xi-2181A and Xi-2181AF bass systems are part of the Xi-A series and are intended for high-level sound reinforcement for fixed-installation and touringsound applications. The Xi-2181A and Xi-2181AF are manifolded, vented-box bass systems utilizing two (2) EVX180B 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. These bass systems are part of the Xi-A series and are intended for high-level sound reinforcement for fixed-installation and touring-sound applications. The Xi-2181A(F) enclosure is constructed of 18-mm, 13-ply, birch plywood and is available in a black textured-paint finish. The flying system includes four fulltrack flying points (two on the top and two on the bottom). Both flying (Xi-2181AF) and non-flying (Xi-2181A) versions are available. The Xi-2181A(F) loudspeaker system is an ideal choice for any professional installation or regional touring application where accurate low-frequency sound reproduction at high sound-pressure levels is required. The Xi-2181A(F) with Dx38 Digital Signal Processor create the ideal solution to subwoofer applications where high acoustic power is required from 41 Hz to 210 Hz. The Xi2181A(F) is designed specifically to be used in conjunction with the full-range Xi-A systems (such as Xi-1122A/85, Xi1152A/64 & /94, Xi-1123A/106, Xi-2123A/106, Xi-1153A/64, Xi-1183A/64, Xi-2153A/64, Xi-1122MHA/64 and Xi2122MHA/42).
