Nexo GEO D10 Tangent Array Module

The high-output D10 array module is centerpiece to NEXO's GEO D vertical tangent array system.

Nexo GEO D10 Tangent Array Module

The optimized 10° Hyperboloid Reflective Wavesource enables multiple GEO D loudspeakers to coherently radiate tangent wavefronts from curved vertical arrays to deliver consistent front-torear SPL across all coverage areas.

GEO D10's patented, third generation Hyperbolic Reflective Wavesource (HRW™), redefines controlled dispersion of acoustic energy, while GEO D10's unique Directivity/ Phase Device (DPD) extends coherency far below the "natural" mid-to-HF coupling limits common to traditional line array system designs. Technically, the legendary HRW controls acoustic energy using an acoustical reflector (i.e. mathematically calculated hyperboloid acoustic mirror, derived from rigorous geometrical transformations) that is functionally positioned "outside" the loudspeaker cabinet.

The DPD extends upper frequency limits for line source coupling between GEO D10's adjacent 12" cone loudspeakers, so that adjacent D10's 12" woofers coherently couple as if there were twice as many 6" loudspeakers, mounted at half the physical distance.

GEO D10's third design signature, the patented Configurable Directivity Device, is a diffraction slot used to control acoustic coverage in the "non-coupling plane" (the horizontal plane of a NEXO
vertical tangent array system).

  • [a] Response curves and data: anechoic far field above 200 Hz, half-space anechoic below 200 Hz.
  • [b] Sensitivity & peak SPL: will depend on spectral distribution. Measured with band limited pink noise. Refers to the specified +/- 3 dB range. Data are for speaker + processor + recommended amplifier combinations.
  • [c] Directivity curves and data: 1/3 octave smoothed frequency response, normalized to on-axis response. Data obtained by computer processing of off-axis response curves.
  • [d] Please refer to the GEO D user Manual.
