The small format TFS-550H Flashline Mini line array is a compact three-way bi-amped line array loudspeaker consisting of a proprietary 1” high frequency compression driver on a Dendritic horn, a proprietary 4” high-mid frequency driver on a Polyhorn™ device, and two Turbo-loaded 6.5” low-mid frequency drivers. In keeping with existing technologies deployed in the larger Flashline and Flex Array systems, the HF Dendritic waveguide features multiple hornlets with identical path lengths designed to give a flat constant phase wavefront with horizontal dispersion of 110°. When coupled to the horn, the waveguide shapes the spherical wave produced by the compression driver into the cylindrical wavefront that is a key component of line source array behaviour. The cabinet is symmetrically loaded to create coplanar symmetry with smooth and consistent horizontal and vertical coverage, creating a co-linear source, the cylindrical domain equivalent of a coaxial arrangement for individual spherical sources. The cabinet is constructed using a polyurethane composite hard foam, making a very lightweight, rigid and non-resonant enclosure. In addition, the precise positioning of the neodymium drive units saves space within the enclosure and enables a very compact package. Rigging hardware is fully integrated into the end-cheeks at the sides of the cabinet. It consists of drop links which engage into the flyware of the cabinet below, secured by captive pins, which stow away on the cabinet when not in use. The rear flyware provides a range of inter-cabinet splay angles from 0° to 12° in one degree increments. The FB-550 flybar provides multiple pickup points located along a central spine, and allows arrays of both mid/high enclosures and bass cabinets to be flown in a visually unobtrusive array. Two rear-mounted Speakon NL4 connectors provide input and link connections to the loudspeaker.
