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.
