The unit includes a deep drawn, ported steel enclosure optimized for low-frequency response, and a front-mounted tap selector that supports 70.7V/100V systems with a bypass for 8-ohm operation. Its detachable 4-pole Phoenix-style connector allows for quick daisy chaining, and the included C-Ring and V-Rail tile bridge ensures easy mounting in new or existing ceilings.
