Description

Featuring the Eighteen Sound elliptical shape technology (ESS), the
XT1464 constant coverage high frequency horn has been developed for use
in sound systems, where the highest quality is required. With a 1.4 in
throat entry, the XT1464 has been designed to exactly match the
Eighteen Sound 1.4 in exit neodymium high frequency compression drivers.
The
XT1464 maintains nominal 60? Horizontal x 50? Vertical pattern control.
It provides consistent on-axis and off-axis frequency response from
800Hz to 15kHz in the horizontal plane and from 1,5kHz to 15kHz in the
vertical plane. Horn directivity is constant from 1.5kHz.
Thanks to
its compact vertical mouth dimensions, the XT1464 can easily be staked
vertically when lower frequency control is required.
The horn
structure made from high-pressure die-cast polyurethane foam eliminates
resonance and vibrations and assures maximum strength.
The XT1464
provides low distortion and a spherical wave-front, avoiding
reflections and other disadvantages usually associated with diffraction
horns. The horn contours were developed using Computer Aided Finite
Element Analysis.
