Bose Corp.","Panaray® LT 9403 loudspeaker is a 3-way, high SPL, full range speaker designed for indoor applications. It features dispersion control and focused coverage with a frequency response of 50Hz - 16kHz and a maximum SPL of 121dB (127db peak). The LT 9403 offers a 93 degree horizontal by 49 degree vertical dispersion which provides consistent on-and-off axis response. The waveguide can be rotated 90 degrees allowing for easier placement of the speaker. Each loudspeaker also includes a 15-inch woofer. Like Panaray LT mid\/high loudspeakers, these full-range models use an innovative Bose® V2 mid-frequency engine. The integrated V2 driver heat sink provides cooler operation and improved reliability. Multiple hang points allow for convenient cluster configuration using industry-standard suspension hardware. Other key features are: - High degree of pattern control allows designers and installers to effectively control dispersion for clearer, more intelligible sound. - Full-range sound with frequency response down to 50Hz helps reduce the need for a separate bass source. An excellent choice for installations that demand full-range sound but cannot accommodate separate bass components. - A waveguide that can be rotated 90 degrees allowing the loudspeakers to be flown vertically or horizontally while still maintaining the same coverage pattern.
Electro-Voice","The XLD281 is the core element for constructing X-Line Very Compact systems. The XLD281 is a three?way design using Coverage Control Technology (CCT™) to provide control horizontal coverage to 250Hz. The XLD281 uses an eight-inch, neodymium, low-frequency transducer, an eight-inch, neodymium, LF\/MB transducer, and two neodymium, two-inch, voice-coil compression drivers combining through two Hydra™ plane wave generators into a 120 degree x 10 degree waveguide. CCT™ uses both eight-inch transducers to provide maximum low-frequency output and operating bandwidth while controlling horizontal beamwidth to 250 Hz by using DSP. The XLD281 can be used in triamp mode, or in biamp using a sophisticated internal passive network. Designed for use in arrays of four or more elements, the XLD281 delivers full-bandwidth audio with precise, predictable coverage control. Integrated rigging with hinge points located correctly between array elements is easy to use and quickly provides uncompromised line array performance. Ground-stacking is easy using array rails or subwoofers as the array base.
