The Electro-Voice
®
Xi-2153A/64F is a full-bandwidth, three-
way, triamp system designed for medium- to long-throw
applications. The orientation of LF section and the mid-
bass horn create a three-element line array that extends
vertical pattern control to below 150 Hz. Using VBS (Vertical
Beam Shaping) technology this benefit can be increased
by another 20° to 50° of pattern control above 200 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. Frequency response on-axis is
unaffected, while gain before feedback is increased by 10
to 15 dB for microphones located under the loudspeaker.
Its high-frequency horn/driver section is rotatable to provide
proper coverage for vertical or horizontal system
installations. The low-frequency section is powered by two
15-inch drivers (EVX-155) in slot-loaded, closed box
configurations providing high sound pressure levels. When
very high levels of extended very low-frequencies are
desired we suggest augmenting with the Xi-2181A or XSUB.
L-Tracks on top and bottom provide flexible suspenstion
for cluster design and application. The ND6-16 high-
frequency driver/horn combination is fully “shrouded” to
preserve midbass wave-front detail, while allowing a
compact coaxial configuration.
