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.
“Our fans who own the suites that received the new audio systems were THRILLED! They loved the clarity and the ease of use. Thank you and your staff for all of your last-minute efforts. It’s nice to deal with people who are willing to go the extra mile for customer satisfaction.”

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.
