Xi-1123A/106F is a triamp-ready, three-
way system in a unique two-element-line-array configuration
designed for use in reverberant spaces. The orientation of
LF section and the mid-bass 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 30° of pattern
control above 300 Hz. VBS uses filters to overlap the LF
section 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-1123A/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-1123A/106 may be coupled with the Electro-Voice Xi-
1191A or Xi-2181A.
