The XR1464C is a 1.4 inch throat entry constant directivity horn. The horn has been developed to reach optimum performances when it will coupled with 1.4 inch exit Eighteen Sound high frequency compression drivers. All XR series horns have been designed in order to reach smooth driver frequency response, to maintain constant coverage and directivity and eliminating the midrange narrowing and high frequency beaming problems common of many similar horns on the market. The XR1464C maintains nominal 60° Horizontal x 40° Vertical pattern control. It provides consistent on-axis and off-axis frequency response from 1,2kHz to 16kHz in both horizontal and vertical planes. Horn directivity is constant down to 1,2kHz DATENBLATT

The XR1496C has been designed in order to obtain a smooth frequency response maintaining constant coverage and directivity pattern, and avoiding the midrange narrowing effect as well as high frequency beaming problems. With a throat entry of 1.4 inch, the XR1496C has been developed to reach the optimum performance when it will coupled with 1.4 inch exit Eighteen Sound high frequency compression drivers. The XR1496C maintains nominal 90° Horizontal x 60° Vertical pattern control, providing consistent on-axis and off-axis frequency response from 1,2kHz to 16kHz in both horizontal and vertical planes. Horn directivity is constant down to 1,2kHz.DATENBLATT

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. DATENBLATT
