The BOSE's LT4402WR is a high-output, mid/high-frequency passive speaker designed for use in Coherent Zone arrays in medium to large permanent installations needing accurate coverage and good intelligibility when combined with other LT loudspeakers. In many stadiums and arenas, the large-format waveguide and narrow 40° x 40° pattern provide a cost-effective alternative to multiple-cabinet line arrays for long-throw applications.
