The TFA-600B is a compact horn loaded bass loudspeaker designed to be ground stacked with Flex Array TFA-600H mid/highs. It consists of a single 18" neodymium low frequency driver loaded with a TurboBass device. The TFA-600B 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 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. Its stacking corner protectors allow TFA-600B cabinets to be ground stacked with TFA-600L (which have integrated flyware) or TFA-600B cabinets. A threaded pole mount socket is fitted for use with flying yokes. A recessed panel at the rear of the cabinet carries two parallel-linked Speakon NL4MP connectors for input and loop-through connections.
