ลำโพงรุ่น BOSE : LT9403 ออกแบบสำหรับใช้งานภายในอาคาร มีคุณสมบัติพิเศษควบคุมการกระจายเสียงและเน้นการกระจายเสียงที่ครอบคลุมไปยังบริเวณที่ต้องการ ด้วยการตอบสนองความถี่ระหว่าง 50 Hz – 16 kHz มีมุมกระจายเสียงในแนวนอน 90° และแนวตั้ง 40°
The Bose® LT 9403 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 90° x 40° pattern deliver precise coverage and high intelligibility, providing a cost-effective alternative to multiple-cabinet line arrays for many applications
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
