The ALA20TAW-B is an EN54-24 certified passive column line array loudspeaker designed for applications that demand superior speech intelligibility and controlled coverage in a sleek, space-saving enclosure. Finished in black, the ALA20TAW-B features twenty tightly packed 3" (76 mm) full-range drivers and six 22 mm high-frequency tweeters housed in a durable extruded aluminum cabinet with a matching powder-coated grille.
With 135° horizontal and 40° vertical dispersion, this speaker ensures wide and even sound distribution, making it ideal for auditoriums, houses of worship, transportation hubs, conference halls, and other large-scale venues. It delivers up to 127 dB SPL peak output with a frequency response of 110 Hz - 20 kHz, providing both powerful projection and natural clarity.
The enclosure's slim profile blends seamlessly into any environment, while the included wall mount bracket allows flexible vertical tilt adjustment. An optional pole mount bracket is available for portable or modular setups, particularly when paired with AtlasIED's A-Line subwoofer systems.
Engineered for reliability and outstanding performance, the ALA20TAW-B is the perfect solution where precision coverage and premium sound reinforcement are required.
Note: Pole and pole mount bracket sold separately.
