World Leaders in Sound Reinforcement
Coherent. Transparent. Faithful.
The high-output sound reinforcement system re-defined.
Technology
In conjunction with a GEO rigging system designed to control angular splay to 0.01 degree precision. NEXO’s groundbreaking Hyperboloid Reflective Wavesource (HRW™) technology produces precise and predictable results, ensuring that GEO T wavesources couple optimally without destructive interference.
The key to GEO T’s success is in the innovative method that the HRW uses to control acoustic energy, empowering users to craft high-output wavefronts to precisely fit audience areas, more coherently and more evenly than previously possible.
The HRW wavesource (see Figure 1) controls acoustic energy with an acoustical reflector – a mathematically calculated hyperboloid acoustic mirror, derived from a rigorous set of geometrical transformations. Thus the HRW creates a virtual acoustic wavesource that is ‘outside’ the loudspeaker cabinet (see Figure 2).
This revolutionary technique allows the designer to locate the real source (the compression driver) almost anywhere inside the enclosure. It also provides a virtual source that is behind the rear of the enclosure. As such, GEO wavesource measurements exhibit a degree of correspondence between mathematical predictions and real word results.
In addition, GEO T employs a Directivity Phase Device (DPD) on each cone driver which extends the upper frequency limit for line source coupling between adjacent woofers, and a Configurable Directivity Device (CDD) which allows system designers to precisely alter wavesource behaviour – particularly useful in optimising systems in permanent installations.

GEO T System Overview
Developed in conjunction with leading PA hire companies and field tested worldwide, the GEO T Series has re-defined high output sound reinforcement. With unique cardioid dipole midbass, as well as the GEO Hyperboloid Reflective Wavesource™, GEO T displays today's most advanced, most efficient and most accurate sound reinforcement technology.
Used at major outdoor festivals including Glastonbury, AcaFest (Mexico), Fleadh (London), S'olidays (Paris) and Carling Weekend (Reading/Leeds UK) GEO T is now the benchmark of vertical arrays.
FOH Engineers for Oasis, The White Stripes, Arctic Monkeys, Morrissey, The Gipsy Kings, Linkin Park, Moby and Tori Amos routinely rely on the coverage, fidelity and SPL of NEXO's large format Tangent Array system.
To provide the highest level of security to GEO T users, the GEO T rigging hardware has been certified by TUV NORD
