Bose LT9702WR High-Output Mid/High Passive Loudspeaker 140w (Black)


Recommendation to retail stadiums, arenas, houses of worship, auditoriums, performing arts venuesand outdoor event venues

Large-format waveguide and 90° x 70° 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.


  • 90° x 70° coverage for short-throw applications in auditoriums, worship facilities, performing arts centers, stadiums and arenas.
  • 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 9702 WR loudspeaker utilizes two Bose V2 midrange manifolds.
  • Bose large-format waveguide provides effective 90° x 70° pattern control to approximately 250 Hz (horizontal) and 500 Hz (vertical). Minimizes loudspeaker overlap in arrays to reduce comb-filter interference and improve intelligibility.
