|NEXO Geo systems incorporate a number
of patented technologies to achieve exceptional accuracy, consistent frequency
and SPL coverage throughout the audience, and close correlation between
mathematical predictions and real-world results.
To achieve coherency
in a line array, multiple cabinets must behave as if they share a single
sound source. Geo systems use NEXO’s groundbreaking Hyperboloid
Reflective Wavesource (HRW™) technology to ensure that wavesources
couple optimally without destructive interference.
The HRW controls acoustic energy with a precision–engineered hyperboloid
acoustic mirror, creating a virtual wavesource located outside the cabinet.
Because the path lengths from the virtual and real sources to the horn
mouths are identical, wavefronts are perfectly in phase at their coupling
points – regardless of where the real sources are located in relation
to the coupling point.
In permanent installations, Geo D and Geo S systems ship with Configurable
Directivity Device Flanges, providing system designers with an unprecedented
degree of control over wavesource behaviour. CDD flanges can be easily
introduced into the waveguides – for instance on the bottom two
cabinets of curved vertical arrays to fill in coverage gaps in the front
rows, or in all cabinets where 120 degrees of horizontal coverage is preferred
to 80 degrees. In horizontal arrays, CDD flanges can be used to widen
vertical coverage from 80 degrees to 120 degrees.
