LT 9400 mid/high loudspeaker


Medium-format waveguide and 90° x 40° pattern designed for downfill applications with LT Coherent Zone arrays in medium to large permanent installations, or as the primary reinforcement source along with MB low-frequency loudspeakers in smaller arrays and venues.

For indoor applications only.


90° x 40° coverage for short- to medium-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 9400 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
