LT 9403 Full Range Loudspeaker - Each

full-range loudspeaker

Medium-format waveguide and 90° x 40° pattern 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.

For indoor applications only.

Key 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
