High-output, mid/high-frequency loudspeaker
ลำโพงรุ่น BOSE : LT9402 WR มีค่าตอบสนองความถี่อยู่ที่ 180 Hz - 16 kHz, มีระยะความถี่อยู่ระหว่างที่ 150 Hz - 18 kHz และมีมุมในการกระจายเสียงแนวนอนและแนวตั้งที่ 90° x 40°
The Bose® LT 9402 WR is a high-output, mid/high-frequency loudspeaker designed for use with other LT loudspeakers to form Coherent Zone arrays in medium to large permanent installations requiring precise coverage and high intelligibility. The large-format waveguide and 90° x 40° pattern provide a cost-effective alternative to multiple-cabinet line arrays for many applications.
Features :
-
90° x 40° coverage for 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 voiceonly 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 9402 WR loudspeaker utilizes two Bose V2 midrange manifolds
-
Bose large-format waveguide provides effective 90° x 40° pattern control to approximately 250 Hz (horizontal) and 1 kHz (vertical). Minimizes loudspeaker overlap in arrays to reduce comb-filter interference and improve intelligibility
