NEXO’s compact, 2-way GEO S1230 is a scalable high­output, loudspeaker module. While a narrow-Q (30°)
device in single-source mode, S1230’s unique Hyperboloid
Reflective Wavesource (HRW) also allows coupled S1230s
to radiate as coherent, wavefronts, in either horizontally
or vertically arrayed systems. GEO S1230’s coupled MF/
HF pattern control is array- dependent, as designed by
GEOSoft2 array software, and configured according to
venue -specific geometry. Non-coupled MF/HF coverage
configures at 80°or 120°.

The S1230 module displays exceptional MF-LF output
(103dBSPL nominal sensitivity -1W @1m) from a
single12” loudspeaker and NEXO’s proprietary Directivity
Phase Device (DPD). Precise, inter-cabinet angle
adjustments, are optimized by integral flying system
hardware while NEXO’s digital N242 TDcontroller
maximizes S1230’s MF/HF coherency.

SYSTEM OPERATION

Electronic Controller NEXO TDcontroller presets are precisely matched to GEO S12 Series cabinets and include
sophisticated protection. Using GEO S12 Series cabinets with improperly connected TDcontrollers
will result in poor sound quality and can damage components.

Array Design Arrays of less than 4x GEO S1210 will provide poor dispersion control and neither
recommended nor supported.

Sub-Bass RS15 / CD18 / GEO SUB / S2 extend system low frequency response down to
35Hz / 32Hz / 38Hz / 32Hz.

Speaker Cables Active: 1-/1+:LF; 2-/2+: HF / Passive: 1-/1+: Not Connected; 2-/2+:LF + HF.
Rigging System Please refer to the GEO S1230 User Manual before operation.

SHIPPING & ORDERING

As part of a policy of continual improvement, NEXO reserves the right to change specifications without notice. [a] Response curves and data: anechoic
far field above 200Hz, half-space below 200Hz. [b] Sensitivity & peak SPL: will depend on spectral distribution.
Measured with band limited pink noise. Refers to the specified ±3dB 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
offaxis response curves. [d]Please refer to the GEO S1230 User Manual. Usable range data: frequency response capability with TDcontroller crossover
slopes removed.
