40° x 40° coverage for long-throw applications in stadiums and arenas (the only large-format waveguide currently available with 40° x 40° pattern)
Large-format waveguide and narrow 40° x 40° pattern designed for use with other LT loudspeakers to form Coherent Zone arrays in medium to large permanent installations requiring precise coverage and high intelligibility.
For indoor and outdoor applications.
40° x 40° coverage for long-throw applications in stadiums and arenas (the only large-format waveguide currently available with 40° x 40° pattern)
Mid/high-frequency loudspeaker designed for use in arrays with separate LF augmentation (Bose® MB12 or MB24 bass arrays) or voice-only applications
Bose V2 midrange manifold sums output of 2 x 4.5″ (114 mm) extended-range cone drivers for lower breakup distortion and improved transient response. Provides a smoother, more natural vocal range compared to single 8″ to 12″ woofers. The LT 4402 WR loudspeaker utilizes two Bose V2 midrange manifolds
Bose coherent zone waveguide provides effective 40° x 40° pattern control to approximately 1 kHz. Minimizes loudspeaker overlap in arrays to reduce comb-filter interference and improve intelligibility
