Nexo GEO D10 TOUR Cardioid Line Array Loudspeaker
The launch of GEO S fulfilled NEXO’s long term design goal to integrate multiple full-range cabinets as scalable systems that behave as high output, full bandwidth, single source systems with full spectrum coherency and precise, pattern control. This rigorously documented and unrivalled sonic signature has earned global acceptance and universal praise for GEO Tangent Array technology.
GEO D continues NEXO’s commitment to GEO systems R&D. It’s10° vertical coverage opens the new system up to users at a three box (per side) minimum, providing exceptional price/performance access to our world class Tangent Array technology.
Flying up to 16x deep, or stage stacked, the powerful GEO SUB can deploy with any GEO system and, when flown, displays powerful LF and VLF response from 38Hz to 300Hz, while maintaining NEXO’s legendary cardioid LF and VLF directional control.
NEXO’s 3-way GEO D10 vertical array module achieves exceptional MF-LF output (105dB SPL nominal sensitivity-1W @1m) from a single 12” loudspeaker coupled to a proprietary Directivity Phase Device (DPD).
GEO D10 vertical MF/HF pattern control is array dependent, horizontal MF/HF coverage is configurable at 80°or 120°. NXAMP maximizes MF/HF coherency while twin 8” side-firing transducers create exceptional cardioid LF coverage.
An integral flying system optimizes venue-specific array design from precise, logarithmic inter-cabinet angle adjustments as configured by NS-1 array software. The Over/Under GEODBUMPER maximizes rigging utility, allowing up to 24x GEO Ds to fly together, or stagestacking of GEO D10 with GEO SUB and CD18.

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.
In line arrays, the physical diameter of cone drivers would appear to make it impossible to achieve interference-free, close coupling of wavesources at the frequencies necessary to crossover with HF drivers. NEXO’s revolutionary Directivity Phase Device causes an 8 inch driver, for instance, to behave as twin 4 inch drivers, with two acoustical centres spaced 5 inches apart, cleverly extending the upper frequency limit for line source coupling between adjacent woofers.
Geo rigging systems deliver control over angular splay to an increment of 0.01 degree, making it possible to configure line arrays of exceptional accuracy and coherence.
Featuring a single, earthshaking, front-mounted 18" transducer, GEO SUB radically advances NEXO’s revolutionary DSP managed, cardioid LF performance. Twin, active side-firing 12" speakers allow flown GEO SUB systems to display tightly focused bass and subbass coverage, while precision, internal venturi porting smoothes performance, virtually eliminating unwanted “porting noise”. The yield exceeds all previous expectations about LF and VLF power and control.
