Large / Medium Format

Bose® large/medium-format loudspeakers include 6 mid/high-frequency loudspeakers, 2 full-range loudspeakers, and 2 low-frequency subwoofers designed for permanently installed sound systems requiring precise coverage pattern control with high intelligibility and excellent  tonal balance. The flexible product line provides scalable solutions appropriate for venues ranging from small 300-seat auditoriums to large stadiums and arenas. For many venues with complex seating-area geometries, the LT Series point-source design often provides more consistent coverage than line array solutions that offer only a single horizontal coverage angle.

All large/medium-format mid/high-frequency and full-range loudspeakers feature the Bose V2 Midrange Manifold. This proprietary Bose technology sums the output of two 4.5-inch extended-range cone drivers mounted in a combination heat-sink/acoustic summation manifold designed to significantly lower cone breakup distortion and improve transient response, compared to single 8” to 12” woofer designs. The result is a smoother, more natural vocal range response.
