Nine compact line arrays sharing one 2" × 2" extrusion — from a 9-inch fill to a 72-inch full-height column. Uniform dispersion, no hot spots, and timbre-matched drivers across the family.

Eight PHA-4 arrays disappear between the wood ceiling slats of this executive boardroom in San Francisco’s Presidio, each driven through a Pragmatic PAT-15 70V/4Ω transformer. The arrays beam straight down onto the seating — almost no energy reaches the glass walls, so reflections stay minimal and every chair hears the same level, with no hotspots. A price-performance combination we’ll put up against any speaker for this class of room — line array or conventional.
In the ceilings of the world’s largest big-box retailer — white-on-white in the rafters, beaming clear audio into the aisles, store after store.
Eight arrays between the ceiling slats, black-on-black beside the light bars — full-range audio, invisible integration.
Gate audio clear across the seating area, all but inaudible at the boarding counter. Staff, when asked: “What audio?”
Five audio zones above five gaming stations — hospitalized kids play different games side by side without disturbing each other.
Mounted above bus-stop displays, running program audio through desert heat, sun and street noise — outdoors, year-round.
Ceiling-mounted above the seats, beaming signage audio onto waiting patients — and off the front-desk staff. The MBA-120 amp hides above the tiles.
Four arrays in one exhibit — two above the main display wall, two above the hall entrances, cutting through trade-show floor noise.
A 53-second look at why line arrays belong on video walls: conventional speakers spray sound everywhere, while a vertical PHA-5125 column focuses it across the room — intelligible from the front row to 10 m back, with no ceiling slap. Corporate boardroom, hospitality lobby and home-theater layouts from the application white paper.
