The AtlasIED DLS4 targets commercial installation professionals who need reliable, low-profile audio coverage in challenging low-ceiling environments. Airports, rail stations, retail stores, and hospitality venues all present unique constraints around aesthetics, code compliance, and ease of installation — the DLS4 addresses all three with a press-fit grille, a small footprint, and compatibility with Atlas Sound hardware for new construction and retrofit applications alike.
Where the DLS4 differentiates itself from competing distributed audio speakers is its patent-pending tap selector knob, which doubles as a high-frequency diffusion cone. This means the 70V/100V system tap can be adjusted after the speaker is fully installed in the ceiling, eliminating the need to remove the unit for system tuning — a significant labor savings on large-scale installs. The 4" high-efficiency paper cone driver delivers broad 105° dispersion and a sensitivity rating well-suited for background music and paging at moderate SPL levels.
For AV integrators working in UL-compliant commercial installs, the DLS4 carries UL1480 and UL2043 safety listings, meeting requirements for fire-rated ceiling plenum spaces. With a 60-month warranty and taps ranging from 0.5 to 8 watts plus an 8-ohm bypass, this speaker offers the flexibility and compliance documentation that commercial AV projects demand.
