TFA-600L Compact Horn-loaded Subwoofer
The TFA-600L is a compact, horn-loaded subwoofer enclosure designed to be flown or
ground stacked with TFA-600H enclosures. It consists of a single 18” neodymium drive unit
loaded with a TurboBass™ device in a birch plywood cabinet. The TFA-600L utilises the same
drive unit as the larger TSW-218 horn-loaded subwoofer and employs the same loading
techniques, so these two bass enclosures can be freely mixed in any application. The
proprietary 18” drive unit is the result of a development project that has produced a unique
neodymium motor system. The magnet system drives a dual-spider, split 4” voice coil which
provides linear BL (magnetic force) with displacement, ensuring optimum control from the
motor assembly and very low harmonic distortion, even at the excursion limits. The 4” voice
coil also results in a lower system moving mass than equivalent 5” units, resulting in higher
sensitivity and exceptional response to fast transient peaks.
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 used to create a stable Flex
Array ground stack. A pole mount socket is provided for use with flying yokes.
The 15mm birch plywood cabinet is equipped with a perforated steel grille with foam backing
and 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 NL4MP
connectors for input and loop-through connections.
