A long-anticipated addition to the company's successful GEO S and GEO T tangent-array designs, GEO D features NEXO's patented, third-generation Hyperbolic Wavesource. Equally innovative is the cardioid GEO SUB bass/sub bass cabinet, which arrays from the same over/under bumper as GEO D, and offers unrivalled pattern-control from new, proprietary NX242 TDcontroller digital filter sets.
Five years experience with GEO Series flying and stage-stacking systems have yielded the most rigging-friendly NEXO sound reinforcement system to date. Equally at home on or above the stage, using a single, elegant hardware system, GEO D can be deployed in minimum arrays of four units per side, while the remarkable GEO SUB, at 140dB-143dB peak, can fly 16 units deep per bumper.
Positioned as the ultimate upgrade, the GEO D/GEO SUB package significantly broadens the potential user base for advanced NEXO's tangent-array technology. Like all NEXO products, GEO D and GEO SUB are subject to advanced EtherSound network integration and control.
Designed by NEXO's in-house team of Eric Vincenot, Francois Deffarges and Frank Gillardeaux (the GEO SUB), the GEO D and GEO SUB are fully compliant with the rest of NEXO's GEO Series technology. GEO D allows an unprecedented entry point to GEO Technology, with a minimum system configuration of only four cabinets per side. For a relatively low investment, a 16-box GEO D (mid-size concert) inventory can be divided into two separate systems, usually with at least one bass/subbass cabinet per side, to handle two smaller events simultaneously.
Most GEO D applications will require one of two available sub-bass options. The GEO SUB bass/sub-bass offers cardioid LF (29Hz to 600Hz) while NEXO's CD18 SubBass is offered for sub bass-only reinforcement.
NEXO's 3-way GEO D vertical array module contains two 8in side-firing active transducers, positioned on the left and right side of the cabinet, with a single 12in ahead of them at the front of the box, coupled to a proprietary Directivity Phase Device (DPD).
While GEO D's vertical MF/HF pattern control is array-dependent, the horizontal MF/HF coverage is configurable to 80° or 120°, and the module achieves exceptional MF-LF output (105dB SPL nominal sensitivity-1W /1m). NEXO's digital, EtherSound-enabled NX242 TDcontroller integrates hi-performance MF/HF response with cardioid LF coverage via the two 8in loudspeakers.
A 16Ω driver/3in voice coil/1.4in throat HF assembly provides unrivalled coherence as mounted to the patented, third-generation, 5° GEO Hyperboloid Reflective Wavesource (HRW).
An important development in the GEO Series is the new compression-mode rigging system developed for GEO D, with logarithmic angles from 0.2° to 10°. The versatile (over/under) GEODBUMPER allows up to 24 GEO D's to be flown together, and also offers a stage-stackable option, giving users maximum rigging flexibility in venues large and small, old and new. This elegant, integral flying system optimises venue-specific array design via precise, logarithmic inter-cabinet angle adjustments as configured by GEOSoft2 array software.
Conventional, omni-directional subwoofers produce nearly equal FOH and on-stage LF levels, overwhelming stage monitor mixes and over-stimulate the reverberant field. Indoors, a 'power alley' produces excessive centre aisle bass and lightweight sidewall LF. Midbass frequencies (80-400Hz) experience similar omni-directional interference.
The GEO SUB is an advanced cardioid bass and sub bass module, displaying exceptional forward gain across the LF- VLF frequency range (29Hz to 600Hz) and eliminates most common omni-directional LF problems. A high-efficiency, front-loaded 18in driver
