SYSTEM OPERATION
Electronic controller The NEXO TDcontrollers presets are precisely matched to the GEO S12 Series cabinets and include sophisticated
protection. Using GEO S12 Series cabinets without a properly connected NEXO TDcontrollers will result in poor sound
quality and can damage components.
Sub-bass CD18 / GEO SUB / S2 extend system low frequency response down to 32 Hz / 38 Hz / 32 Hz

[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 S12 user Manual.
Usable range data: frequency response capability with TD crossover slopes removed.
