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.
