Page 7: Introduction
The TA-500 trapezoidal enclosure can be ground-stacked or flown in arrays. It can also be integrated with TA-880 or TA-890 systems as a front or side fill cabinet. -
Page 8: The Aspect Polyhorn™ Concept
Because of the Polyhorn™ design’s sharp cut-off, its array angle can in practice be taken as being the same as the dispersion angle. Fig 1. Conventional HF horns produce destructive interference TA-500 user manual Page 8 Fig 2. Poyhorn™ creates smoothly curved and phase-coherent wavefront... - Page 9 • The TA-500 features approximately twice the horizontal and vertical dispersion as the narrower TA-880 and TA-890 products, making it more suitable for medium- and near-field applications in smaller rooms. • The Polyhorn™ displays a similarly sharp cut-off at the dispersion edges to the...

Page 15: B18 Subwoofer
The B18 is a compact bandpass subwoofer designed to be used in a variety of installed sound system applications as well as portable sub-bass support for Aspect TA-500 enclosures. It consists of a high-excursion, 4” voice-coil, 18” LF driver in a bandpass birch plywood enclosure of modest dimensions. -
Page 16: Transportation
An optional WB-500 wheelboard is available which clips on to the front of the cabinet, allowing single units to be conveniently transported. These are designed to be stackable, so that when not in use they can be neatly stored without taking up unecessary floor space. TA-500 user manual Page 16... -

Obtain a smooth even curve in the horizontal plane. • Use a similar amount of tilt on each column. • Ensure that the bottom corners of each column are in line with each other. user manual TA-500 TA-500 user manual Page 17... -
Page 18: Safety Notes On Rigging
Only use Turbosound recommended rigging accessories, which are specifically designed for their intended purpose. Do not use Turbosound rigging with other types or brands of loudspeakers. This practice may compromise safety standards and Turbosound will not be responsible for damage or injury so caused. -
Page 19: Secondary Safeties
Users must ensure compliance with all applicable safety requirements. Turbosound recommends regular safety inspections and further recommends that a logbook be kept detailing the test and inspection history of each Turbosound rigging accessory. Turbosound has adopted the following load safety factors: •... - Page 20 The Lifting Operations and Lifting Equipment Regulations 1998 Each component is covered by a Record of Load Test Certificate, which may be obtained on request from Turbosound, quoting the indentifying number(s) from the flying equipment. A copy of a sample certificate is reproduced overleaf.

Page 22: Flying Hardware
Because the Polyhorn’s design dramatically reduces the acoustic energy outside of the specified 50° horizontal dispersion pattern, it is recommended that Aspect TA-500 enclosures always be arrayed in a smooth even curve, resulting in an array angle of 50° between boxes. -
