The T4805 Vertical Tangent Array Module is the most advanced Expression yet of Nexo's patent-pending GEO Technology. It incorporates the Hyperboloid Reflective Wavesource, the Configurable Directivity Flange, the Directivity Phase Device and a unique DSP-driven cardioid LF section.
Multiple T4805s and T2815s combine to form a single very high output source of coherent acoustic energy. GEOSoft, our compiled Matlab application, makes it easy to determine the wavefront curvature that will deliver equal power to equal areas in any Venue.
Like its Long-Throw partner, the T4805, the innovative T2815 Tangent Array Module incorporates the patent-pending GEO Hyperboloid Reflective Wavesource. This unique device for controlling acoustic energy makes GEO T the only concert-level sound system in existence that is capable of seamless, coherent nearfield/downfill coverage.
The T2815 controls midbass energy with a unique cardioid dipole that pairs the front-firing woofers with resistive acoustic radiators. When used as the nearfield element in a curved vertical Tangent Array with T4805 modules, the T2815's passive radiators enable it to generate a consisent 120deg dispersion in the non-coupling plane from 77-250Hz. When the T2815 is used on its own as a horizontal Tangent Array module, the acoustic resistors can be closed off to allow 6dB more forward gain (at the expense of some loss of directional control in the lower octaves).
