The Electro-Voice
®
Xi-2123A/106F is a triamp-ready, three-
way system in a unique three-element-line-array
configuration designed for use in reverberant spaces. The
orientation of LF sections and the mid-bass horn create a
three-element line array that extends vertical pattern control
to below 250 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 sections bandpass with mid-bass 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. The DL10X 10-inch mid-bass driver
features RMD™ and is coupled to a rotatable 100° x 60°
vertical horn. The high-frequency system uses an ND6-16
large-format compression driver with a rotatable 100° x 60°
horn. It is mounted within the upper woofer enclosure to
provide a compact vertical size. The Xi-2123A/106 is ideally
suited for high-level, high-fidelity applications. The system
is particularly suited where extended vertical polar control
is necessary. Its low-frequency capability allows the system
to be used in many applications without a subwoofer. For
applications requiring very high low-frequency sound
pressure levels as well as very accurate vocal reproduction,
the Xi-2123A/106 may be coupled with the Electro-Voice Xi-
1191A or Xi-2181A.
