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.

Bose LT6403 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 insmaller venues
  • Bose® V2 midrange manifold sums output of 2 x 4.5"(114 mm) extended-range cone drivers for lower breakup distortion and improvedtransient response. Provides a smoother, more natural vocal range compared tosingle 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
