NEXO Line Array Systems: A Legacy of Innovation and a Future of Precision

For more than four decades, NEXO has been one of the most respected names in professional sound reinforcement. Known for compact designs, exceptional output-to-size ratios and a signature clarity that appeals to engineers across live music, theatre, corporate events and touring, NEXO has continuously refined what a line array can be. Their approach has always balanced practical deployment with advanced acoustic engineering, creating systems that are as efficient on the road as they are impressive in the air.

Early Innovations and the Birth of Compact Line Arrays

NEXO began shaping the modern line-array market long before the format became mainstream. Early systems such as the GEO S and GEO T helped introduce concepts that became industry standards: sculpted waveguides, precision-controlled directivity and compact enclosures capable of covering surprisingly large audiences. The GEO T4805 and T2815 were groundbreaking at the time, offering high-powered touring performance in cabinets that delivered tight pattern control without the size of traditional long-throw systems.

The GEO S8 and later the GEO S12 took these ideas further. These arrays proved that a compact system could offer enough punch and clarity for mid-sized festivals, theatres and churches. They became popular for their flexibility; engineers could adapt them to almost any room thanks to NEXO’s proprietary Hyperbolic Reflective Waveguide technology, which maintained coherence and coverage in challenging acoustic spaces.

GEO S12 and the Arrival of Workhorse Reliability

The GEO S12 series became one of NEXO’s most recognisable product lines. Many rental houses still use S12 today because it strikes a balance between power, durability and ease of deployment. S1230 and S1210 cabinets provided variable horizontal coverage and excellent vocal presence, making them a favourite for corporate events, medium-scale touring acts and production companies wanting a reliable, go-anywhere array.

STM: The Modular System That Changed the Game

NEXO’s STM system marked a turning point. Instead of traditional fixed-format arrays, STM introduced a completely modular concept, allowing engineers to build a PA that could scale from a club gig to a full arena system using the same components. STM stood for Scale Through Modularity and included the M46 main module, B112 bass module, M28 compact module and the S118 sub. This approach gave rental companies flexibility and excellent return on investment because the same inventory could cover almost any scenario.

The sound signature of STM was characterised by precision, aggressive punch when required and a notable ability to maintain consistency across different configurations. STM systems are still widely used today in large-format touring, festivals and high-profile events.

The Modern Era: GEO M Series

NEXO’s current flagship line-array offerings sit within the GEO M family. These systems refine everything the brand has learned over decades while embracing the latest driver technology, cabinet materials and processing.

The GEO M6 is an ultra-compact array designed for speech, theatre, houses of worship and small live venues. Its strength lies in delivering smooth, articulate reinforcement with extremely even coverage in a tiny footprint. Despite its size, it integrates seamlessly into larger NEXO systems when required.

The GEO M10 represents the next step up, delivering greater output and bandwidth for small-to-medium touring, corporate work and outdoor events. It maintains NEXO’s hallmark coherence and uses a choice of horizontal directivities, allowing designers to tailor coverage to complex architectural spaces.

The GEO M12 is currently the highest-powered system in the M series. It offers full-scale line-array performance for festivals, arenas and large event spaces, while remaining considerably lighter and more compact than traditional “big box” systems. Many engineers appreciate how easy it is to tune; NEXO’s processing and cabinet design create a system that typically requires minimal corrective EQ to achieve a natural, musical response.

Subwoofers and System Integration

NEXO’s philosophy extends beyond the arrays themselves. Their subwoofers, including models like the MSUB18 and LS18, are designed to integrate seamlessly with GEO and STM systems. This ensures coherent low-frequency coverage, which is essential for modern touring and electronic music events. Their NUAR and NXAMP amplification platforms tie everything together, offering precise control, preset optimisation and network integration.

Why NEXO Remains a Trusted Choice

NEXO line arrays continue to be respected because they combine practical deployment with sophisticated engineering. Their systems often weigh less, fly faster and require fewer amplifiers than comparable alternatives, which makes them attractive for both rental houses and venues seeking high performance without excessive technical overhead. Their legacy products still appear in theatres, concert halls and touring rigs worldwide, a testament to their durability and forward-thinking design.

Conclusion

From the early GEO systems that helped shape compact line-array philosophy to the modular power of STM and the refined, modern GEO M series, NEXO has consistently delivered systems built with intelligence, clarity and adaptability in mind. Whether in a small theatre or a major festival environment, their line arrays offer reliability, precision and the unmistakable NEXO sonic character that has made the brand a mainstay in professional audio for decades.
