The TFA-600L is a compact horn loaded bass enclosure designed to be flown or ground stacked with Flex Array TFA-600H mid/highs. It consists of a single 18" neodymium low frequency driver loaded with a TurboBass device in a birch plywood cabinet. The TFA-600L utilises the same low frequency drive unit as the larger TSW-218, and employs the same loading techniques so these two bass enclosures can freely be mixed in any application. The enclosure is equipped with an integrated flying system which enables it to be flown at the top of a column of Flex Array loudspeakers using a simple conversion frame between the bass enclosures and mid/highs. The same conversion frame is also used to provide a stable Flex Array ground-stack. A threaded pole mount socket is fitted for use with flying yokes. The 15mm birch plywood cabinet is equipped with recessed handles on the sides and back, and is supplied with heavy duty wheels in order to aid trucking and handling. A recessed panel at the rear of the cabinet carries two parallel-linked Speakon NL4 connectors for input and loop-through connections.
