The Bose LT 4402 WR is a high-output, mid/high-frequency loudspeaker designed for use with other LT loudspeakers to form Coherent Zone arrays in medium to large permanent installations requiring precise coverage and high intelligibility. The large-format waveguide and narrow 40° x 40° pattern provide a cost-effective alternative to multiple-cabinet line arrays for long-throw applications in many stadiums and arenas.
Applications:
Bose® LT Series loudspeakers are comprised of 6 mid/high-frequency loudspeakers, 2 full-range loudspeakers and 2 low-frequency subwoofers, all designed for permanently installed sound systems that provide precise coverage pattern control, with high intelligibility and excellent tonal balance for music sources. The flexible product line provides scalable solutions appropriate for venues ranging from small 300-seat auditoriums to large stadiums and arenas. The classic point-source design approach of Bose LT Series loudspeakers provide an effective alternative to multiple-cabinet line arrays for many venues, often providing more uniform coverage for complex seating area geometries.
All Bose LT Series mid/high-frequency and full-range loudspeakers feature the Bose V2 Midrange Manifold. This proprietary Bose technology combines the output of two (2) 4.5-inch extended-range cone drivers in a combination heat-sink/acoustic summation manifold, to significantly lower cone breakup distortion and improve transient response as compared to single 8" to 12" woofer designs. The result is a smoother, more natural vocal range response.
