Nexo GEO SUB Directional Sub-bass

When flown, up to 16x deep, GEO SUB arrays provide a sub and subwoofer system for GEO D, GEO S or GEO T, effectively crossing over as high as 300Hz.

With peak SPL of 139-142dB, GEO SUB's front-loaded 18" transducer integrates exceptional high power handling with an extended frequency range.

When stage stacked, the flexible GEO SUB deploys with GEO D10 as a cardioid subwoofer system, allowing end-users infinite scalability and system placement options, with subbass response down to 35Hz.

Rooted in NEXO's ongoing commitment to precise LF control, the unique GEO SUB design employs two side-firing 12" speakers to create unrivalled, cardioid midbass and subbass coverage.

[a] Response curves and data: anechoic far field above 400 Hz, half-space anechoic below 400 Hz. Usable range data: frequency response capability with TD crossover slopes removed.
[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.
