TA-890
INTRODUCTION
Turbosound Aspect System Concepts
The TA-890 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 concert touring applications 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, the Polyhorns develop a more consistent frequency response across all seats of an auditorium with minimal interference between adjacent enclosures.
The Turbosound Polyhorn™
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 a phase-coherent and smoothly-curved wavefront which matches the array curvature, whose centre becomes the virtual point source.
