INTRODUCTION
Turbosound Aspect System Concepts
The TA-880 system is a modular point source loudspeaker system designed to deliver
extremely high fidelity audio. The system is easily scaleable from large and medium scale
ground-stacked and flown concert touring down to small clubs and events.
The Aspect system concept centres around the exceptional directivity of the patented
Polyhorn™ devices employed in the high frequency and high-mid frequency sections of the
mid/high enclosure. In contrast to the majority of conventional horns, Polyhorns develop
more consistent frequency response across all seats of an auditorium with minimal
interference between adjacent enclosures.
The patented Polyhorn™ devices – employed in both the high frequency and high-mid
frequency bands – exhibit a sharp cut-off at the edges of the dispersion pattern, making it
possible to produce seamless coverage of a venue with minimal destructive interference
between elements, however many individual enclosures are deployed in the cluster. The
Polyhorn™ devices generate phase-coherent and smoothly-curved wavefronts which match
the array curvature, whose centre becomes the virtual point source.
The TA-880H trapezoidal mid/high enclosure forms the main component of ground-stacked
or flown arrays. It can also be employed as a front or side fill cabinet. The TA-880HM high-
mid enclosure and TA-880LM low-mid enclosure are available for use in specific fill
applications to cover near-field audience areas such as downfills or front-of-stage fills. The
TA-880L low frequency enclosure is designed to be ground stacked in bass arrays as well as
providing ground support for TA-880 enclosures.
