About this item

Compact line array wall-mountable column speaker ideal for applications including retail stores, concourses, transit spaces, fill applications, conference rooms, architectural spaces, audio for video, and lecture halls. Switchable voicing provides flat response in music mode or mid-range presence peak in speech mode.
Consistent vertical coverage achieved through analog delay beam-forming and amplitude tapering, ensuring clear and even sound distribution without narrow beaming or out-of-coverage lobing.
Dynamic SonicGuard overload protection ensures reliable performance and prevents speaker damage, making it an ideal choice for professional applications. Power Capacity (8 ohm setting): 150W (600W peak). Max SPL: Speech mode: 115 dB (121 peak). Music mode: 111 dB (117 peak). Frequency Range (-10 dB): 80 Hz – 20 kHz. Sensitivity (2.83V@ 1m): 93 dB (speech mode, 2 kHz - 14 kHz) 89 dB (music mode, 300 Hz - 18 kHz)
Versatile mounting options with the included swivel (pan) / tilt wall bracket, allowing enhanced aiming for flexible installation. The drivers feature dual neodymium magnets for light weight. Copper-capped pole pieces lower both the driver inductance and the flux modulation. This increases high frequency extension and reduces distortion at high drive levels. Butyl rubber surrounds provide long life even in high humidity environments. The drivers are shielded.
Built-in 70V/100V transformer and 8 ohm direct capability offer flexibility for integration into various sound systems, making it suitable for professional audio setups in retail stores, conference rooms, and lecture halls. 70V/100V Transformer Taps: 60W, 30W, 15W, (7.5W at 70V only), and 8 ohm thru via switch.
