TSW-218 Subwoofer
The TSW-218 is designed to cover the sub and
low frequency ranges from 25Hz to 100Hz, and
can be used as part of a 5-way Aspect system in
order to reinforce sub-bass frequencies. It
utilises two custom designed neodymium 18”
drivers loaded with TurboBass™ devices. The
proprietary loading technique and horn flare
design produces significant mutual coupling
between adjacent enclosures, resulting in
sensitivity gains of up to 110dB with eight units coupled.
TA-890H Mid-high Enclosure
The TA-890H enclosure covers frequencies
above 100Hz and contains a total of five drive
units. A pair of 10” neodymium low-mid
frequency drivers loaded with TurboMid™
devices covers the frequency range from
100Hz to 400Hz. The low-mid drivers are rear-
facing in the enclosure, providing not only
additional cooling by placing the
magnet/heatsink assemblies in the path of the
airflow, but also acting as phase plugs. A
specially developed 10” low-mid driver
loaded with a LMF Polyhorn™ device covers the range from 400Hz to 4kHz. The remaining
frequencies are covered by a pair of 50mm dome drivers loaded with Polyhorn™ waveguides
specifically designed for this purpose.
The TA-890H mid-high enclosure is designed to provide a precise array angle of 25º
horizontal x 15º vertical. This high Q provides the projection necessary for true long throw
applications such as large arena and outdoor productions.
The Polyhorn™ and TurboMid™ devices are unique to Turbosound and are covered by
principle patents world-wide. They utilise specialised forms of horn loading which provide
exceptionally low distortion and high efficiency from cone-type drive units. The subjective
effect of these devices is greater clarity and transparency of reproduction when compared
with conventional compression drivers and horns.
The TA-890H is fully equipped for all touring applications with independent flying systems.
This allows cabinets to be configured horizontally providing considerable flexibility of use.
