AtlasIED ALX-4D-B ALX-D Digitally Steerable Column Array Loudspeaker | 4 Speakers

The AtlasIED ALX-4D-B is engineered for systems integrators and audio designers tackling acoustically hostile environments — large houses of worship, passenger terminals, transportation hubs, and public assembly spaces where reverberation and reflective surfaces compromise speech intelligibility. By assigning an independent DSP channel and Class-D amplifier to each of its four full-range Neodymium transducers, the ALX-4D-B enables granular beam shaping that column arrays with shared amplification simply cannot match. The result is tightly controlled vertical directivity that maximizes the direct-to-reverberant ratio and places acoustic energy precisely where the audience is seated.

Dante and AES67 are built in as standard, eliminating the network bridges and external interfaces that complicate competing digital beam-steering solutions. Vertical steering and opening angle are both digitally variable, and the acoustic center can be repositioned across the full column length, giving designers the flexibility to optimize coverage without physical repositioning. Independent split beams add a second layer of zoning capability for complex seating arrangements or balcony coverage scenarios.

The ALX-4D-B integrates with AtlasIED GLOBALCOM via the GCK advanced notification software, making it a credible choice for life-safety and emergency sound systems where telemetry, redundancy, and clear message intelligibility are regulatory requirements. The slim cabinet profile and low-profile mounting hardware make it unobtrusive in architecturally sensitive venues, and the modular ALX-D system design means arrays can be shipped and assembled on-site without the logistics challenges of a single long column enclosure.
