0. Introduction
The X-Line loudspeaker systems represent an important step in line-array technology for large- scale sound reinforcement. The individual loudspeaker drivers, acoustic lenses, acoustic waveguides, enclosures and rigging hardware were all designed specifically for the X-Line product line to not only achieve the highest acoustic output with the highest fidelity, but also to produce a precise wavefront from each element to achieve state-of-the-art line-array performance. A brief description of the product line is included below.
Xvls: Three-way, LF/MB/HF loudspeaker system with a 90°H x 5.0°V coverage pattern. The system includes two EVX155Plt 15-inch (381-mm) LF drivers, two ND08 8-inch (203-mm) MB drivers and three ND6-16 3-inch (76-mm) HF drivers. The Xvls utilizes the standard rectangular X-Line shell with rigging, and may be rigged or stacked right-side-up or upside-down for mirror image arrays.
Xvlt: Three-way, LF/MB/HF loudspeaker system with a 120°H x 8.5°V coverage pattern. The system includes two EVX155Plt 15-inch (381-mm) LF drivers, two ND08 8-inch (203-mm) MB drivers and three ND6-16 3-inch (76-mm) HF drivers. The Xvlt utilizes a trapezoidal enclosure with rigging that has the same outside dimensions as the rectangular X-Line shell. The enclosure is trapezoidal in the vertical plane (with a 5.0° total included angle) to minimize space between boxes with greater vertical splay angles. The Xvlt enclosures may be rigged or stacked right-side- up or upside-down for mirror image arrays.
Xsub: Subwoofer loudspeaker system with two EVX180B 18-inch (457-mm) woofers. The Xsub utilizes the standard rectangular X-Line shell with rigging, and may be rigged or stacked right- side-up or upside-down for mirror image arrays.
Xfil1 & Xfil2: Three-way, LF/MB/HF downfill loudspeaker systems with a 120°H x 40°V coverage pattern. The system includes two EVX155 15-inch (381-mm) LF drivers, two ND08 8-inch (203-
mm)MB drivers and two ND6-16 3-inch (76-mm) HF drivers. The Xfil1 and Xfil2 utilizes a front- slanted enclosure with rigging that has the same outside dimensions as the rectangular X-Line shell. The enclosure slant allows for maximum downward coverage with a minimum space between it and the enclosure above. The Xfil systems may not be turned upside down so the Xfil1 and Xfil2 are mirror image systems. The Xfil1 has the HF on the right, while the Xfil2 has the HF on the left.
