Column 8 places eight 2.2-inch full-range drivers in a 610mm enclosure; Column 16 doubles that count in a 1.1m cabinet. Both cover 150 degrees horizontally, with vertical patterns of 7 and 5 degrees respectively. The narrow vertical beam is intended to keep energy off floors and ceilings in churches, conference rooms and reverberant public spaces.
Each model supports 8-ohm operation and 70V or 100V lines. Fitting the supplied connector cover provides an IP54 rating, and black or white cabinets can be repainted. A pan-and-tilt wall bracket, safety tether and spare grille cloth for painting are included.
For installation loudspeakers, brackets, weather treatment, finishing and site labour influence total cost as much as the box. Optimal Audio includes those practical parts and supplies speech and music presets for its Zone and WebApp ecosystem, giving installers a repeatable starting point.
