The Bose® LT 9403 is a full-range 3-way loudspeaker designed as the primary reinforcement source for smaller venues, or for use with other LT loudspeakers to form Coherent Zone arrays in medium to large venues. The large-format waveguide and 90° x 40° pattern deliver precise coverage and high intelligibility, providing a cost-effective alternative to multiple-cabinet line arrays for many applications.

Applications:

• Indoor Arenas
• Houses of Worship
• Auditoriums
• Performing Arts Venues
  
  

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.

• 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
