 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 touring-
sound applications. The Xi-2181A and Xi-2181AF are
manifolded, vented-box bass systems utilizing two (2) EVX-
180B 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 full-
track 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 Xi-
2181A(F) is designed specifically to be used in conjunction
with the full-range Xi-A systems (such as Xi-1122A/85, Xi-
1152A/64 & /94, Xi-1123A/106, Xi-2123A/106, Xi-1153A/64,
Xi-1183A/64, Xi-2153A/64, Xi-1122MHA/64 and Xi-
2122MHA/42).
