LT 4402® WR

high-output mid/high loudspeaker

Large-format waveguide and narrow 40° x 40° pattern designed for use with other LT loudspeakers to form Coherent Zone arrays in medium to large permanent installations requiring precise coverage and high intelligibility.

For indoor and outdoor applications.

  • Stadiums
  • Arenas
  • Houses of worship
  • Auditoriums
  • Performing arts venues
  • Outdoor event venues

Key Features

  • 40° x 40° coverage for long-throw applications in stadiums and arenas (the only large-format waveguide currently available with 40° x 40° pattern)

  • Mid/high-frequency loudspeaker designed for use in arrays with separate LF augmentation (Bose® MB12 or MB24 bass arrays) or voice-only applications

  • 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 4402 WR loudspeaker utilizes two Bose V2 midrange manifolds

  • Bose coherent zone waveguide provides effective 40° x 40° pattern control to approximately 1 kHz. Minimizes loudspeaker overlap in arrays to reduce comb-filter interference and improve intelligibility
