Bose LT 9403 Full Range Loudspeaker for large spaces, churches, schools
Bose LT 9403 is a 90° x 40° pattern designed and medium-format waveguide as the primary reinforcement source for smaller venues, or it can also be use with other LT loudspeakers to form Coherent Zone arrays in medium to large venues.
For indoor applications only.
Features
90° x 40° coverage for short-throw applications in auditoriums, worship facilities, performing arts centers and arenas
Full-range loudspeaker with single 15” (381 mm) woofer provides 50 Hz bass to reduce need for additional low-frequency speakers in smaller venues
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 9403 loudspeaker utilizes a single Bose V2 midrange manifold
Bose large-format waveguide provides effective 90° x 40° pattern control to approximately 300 Hz (horizontal) and 1.5 kHz (vertical). Minimizes loudspeaker overlap in arrays to reduce comb-filter interference and improve intelligibility
