Focus. Fidelity. Flexibility.


Fixed or mobile systems? Vertical or horizontal arrays? GEO S12 presents elegant, ergonomic sound reinforcement solutions for any application, with EN54 versions certified as complying with the EN54 standards for voice alarm systems.


The two-box GEO S12 Series expands GEO’s global reputation for advanced Vertical array design, into horizontal arrays. And system flexibility is extended yet further by the availability of special ‘ST’ long-throw versions of both cabinets, perfect for use in sports arenas.


System Design

Designing and configuring the perfect GEO S12 system is easy using free NS-1 software – a powerful and intuitive system configuration and simulation tool with an intuitive drag and drop interface, ensuring uniform SPL coverage of any NEXO system in any venue.



GEO S12’s patented, fourth generation Hyperbolic Reflective Wavesource (HRWTM), provides precise vertical and horizontal control of acoustic energy, while the GEO Series’ unique Directivity/ Phase Device (DPD) extends coherency far below traditional mid-to-HF coupling limits of ‘common’ arrayed loudspeaker systems.



GEO S12 comprises S1210 (with shallow tapering to the cabinet rear) and S1230 modules (with steeper tapering, allowing for larger array angles), each available in special ‘ST’ long-throw versions for deployment in sports arenas. All cabinets are also available in EN54 versions which are certified as complying with the EN54 standards for voice alarm systems.


Power & Processing

NEXO NXAMPs feature processing pre-sets for every NEXO cabinet along with EtherSound, dante or AES networking options, making it quick and easy to configure GEO S12 systems in a wide variety of applications.



Flexibility of the GEO S12 system is further enhanced by a comprehensive range of mobile touring and fixed installation accessories.
