$4,254.31
The Bose® LT 6403 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 60° x 40° pattern
deliver precise coverage and high intelligibility, providing a cost-effective alternative to multiple-cabinet line arrays for many applications.

Description
Key Features
• 60° x 40° coverage for medium-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 6403 loudspeaker utilizes
a single Bose V2 midrange manifold
• Bose large-format waveguide provides effective 60° x 40° pattern
control to approximately 800 Hz (horizontal) and 1.5 kHz (vertical).
Minimizes loudspeaker overlap in arrays to reduce comb-filter
interference and improve intelligibility
