About the NEXO Geo S Series
The NEXO Geo S Series is a patented complete line array system designed to deliver a high-quality listening experience for smaller audiences. The system is built around tangent array modules including the Geo S805 and Geo S830, each featuring an 8-inch neodymium hi-flux 16 ohm LF driver paired with a 1-inch throat neodymium HF driver on a Hyperboloid Reflective Wavesource. The S805 serves as the main building block for curved vertical tangent arrays, while the S830 handles horizontal arrays and downfill. Complementing the cabinets, the CD12 HyperCardoid Subbass uses two 12-inch long excursion neodymium drivers to create a 120-degree hypercardioid pattern and can be flown or ground-stacked. System control is handled by the NX242 Digital TDcontroller, providing comprehensive DSP management across multiple configurations. A dedicated GEO Flying System enables safe and flexible rigging of the tangent arrays.
NEXO Geo S Series — buyer FAQs
What is the NEXO Geo S Series and what type of audience is it designed for?
The NEXO Geo S Series is a patented complete line array system built for smaller audiences. It centres on tangent array module cabinets that control the dispersion of acoustic energy with a high degree of precision. The system is modular, pairing main array cabinets with a hypercardioid subbass and a dedicated digital controller to deliver a full, managed loudspeaker solution in a single ecosystem.
What are the key differences between the Geo S805 and the Geo S830 modules?
Both modules share the same 8-inch neodymium hi-flux 16 ohm LF driver and 1-inch throat neodymium HF driver, but their Hyperboloid Reflective Wavesources differ in angle: the S805 uses a 5-degree wavesource and is the primary building block for curved vertical tangent arrays, while the S830 uses a 30-degree wavesource for horizontal arrays and as a tangent downfill element in curved vertical configurations.
What does the CD12 HyperCardoid Subbass contribute to a Geo S Series system?
The CD12 uses two 12-inch long excursion neodymium drivers, each controlled by a dedicated DSP channel, to generate a 120-degree by 120-degree hypercardioid pattern. This directional low-frequency output reduces stage spill and rear energy. The CD12 can be flown or ground-stacked, giving engineers flexibility in how they integrate it with the tangent array cabinets above.
Who makes the NEXO Geo S Series and where does it sit in their product range?
NEXO is a French professional loudspeaker manufacturer, a wholly owned subsidiary of Yamaha Corporation since 2008, known for line arrays, point-source loudspeakers, subwoofers and amplified controllers for touring and installation. The Geo S Series sits within their line array offering and is specifically positioned at the smaller-audience end of that range, where precise tangent array technology is still required but on a more compact scale.
What should I check when buying a used second-hand NEXO Geo S Series system?
Confirm which modules are included, since a complete system spans S805 or S830 array cabinets, the CD12 subbass and the NX242 Digital TDcontroller. Check that the NX242 firmware is current, as NEXO updates DSP algorithms regularly. Also verify that any flying hardware is present, because inclinometers and laser aiming devices are essential for correct array deployment.
