0. Introduction
The XLC (X-Line Compact) loudspeaker systems represent an important step in line-array technology for small- and medium-scale sound reinforcement. The individual loudspeaker drivers, acoustic lenses, acoustic waveguides, enclosures and rigging hardware were all designed specifically for the XLC 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. The XLC loudspeaker systems are shown in Figure 1 with key dimensions and weights.
XLC-127:Three-way, LF/MB/HF loudspeaker system with a 120°H x 7.0°V coverage pattern. The system includes one DL12ST 12-inch (305-mm) LF driver, two DM65 6.5-inch (165-mm) MB drivers and two DH2T-16 2-inch (51-mm) HF drivers. The XLC-127 has a switchable crossover that allows either biamp or triamp operation. The XLC-127 utilizes an enclosure that is trapezoidal in the vertical plane (with an 8° total included angle) and has the standard XLC 8° rigging frame secured to the left and right enclosure sides.
XLC-127+:Three-way, LF/MB/HF loudspeaker system with a 120°H x 7.0°V coverage pattern. The system includes one DL12ST 12-inch (305-mm) LF driver, two DM65 6.5-inch (165-mm) MB drivers and two ND6-16 3-inch (76-mm) HF drivers. The XLC-127+ has a switchable crossover that allows either biamp or triamp operation. The XLC-127+ utilizes the same 8° trapezoidal enclosure as the XLC-127 and has the same standard XLC 8° rigging frame secured to the left and right enclosure sides.
XLC-118:Subwoofer loudspeaker system with one EVX180B 18-inch (457-mm) woofer. The XLC-118 utilizes an enclosure that is trapezoidal in the vertical plane (with a 12° total included angle) and has the standard XLC 12° rigging frame secured to the left and right enclosure sides.
