About the NEXO 45N
The NEXO 45N is a stage monitor speaker that applies line array technology to floor monitoring applications, offering a scalable solution for musicians, contractors and rental companies. Its 45-degree waveguide features a curved, smile-shaped exit rather than a conventional rectangular form, creating a virtual acoustic source behind the cabinet to eliminate interference between wavefronts when units are locked together. A magnetic locking system allows multiple cabinets to combine into monitor arrays for higher SPL and wider coverage. The 45N is designed to work with NEXO NXAMP or NUAR racks, which provide channel-by-channel preset selection for amplification and processing across a series of cabinets.
NEXO 45N — buyer FAQs
What is the NEXO 45N and what makes its waveguide design distinctive?
The NEXO 45N is a stage monitor speaker that applies line array technology to floor monitoring. Its waveguide radiates high frequencies at 45 degrees through a curved, smile-shaped exit rather than a conventional rectangular one. This shape accounts for the curvature of a virtual acoustic source projected behind the cabinet, preventing interference between wavefronts when multiple cabinets are locked together into an array.
How does the magnetic locking system on the 45N work in practice?
The 45N uses a built-in magnetic locking system to join cabinets together without additional hardware. Because there is only one cabinet format, multiple units can be combined into monitor arrays to increase SPL and widen coverage. The single-box approach means no secondary wedge or fill module is needed; scaling up is a matter of adding more 45N units and locking them in place.
What amplification and processing does the 45N require?
The 45N is designed to work with NEXO NXAMP or NUAR racks, which provide channel-by-channel preset selection covering all NEXO cabinet types. Running a series of 45N monitors through these racks allows amplification and processing to be configured per channel, making it straightforward to manage multiple monitors across a stage from a single rack-based system.
Who makes the NEXO 45N and where does it sit in the brand's range?
The 45N is made by NEXO, a French professional loudspeaker manufacturer founded in 1979 and based near Paris, where it designs and builds its products. NEXO is known for line arrays, point-source loudspeakers, subwoofers and amplified controllers for touring and installation, and has been a subsidiary of Yamaha Corporation since 2008. The 45N represents the brand's application of line array thinking specifically to stage monitoring.
What should I check when buying a used NEXO 45N?
When buying a second-hand 45N, confirm the magnetic locking mechanism engages cleanly, as this is central to building monitor arrays. Check the waveguide for physical damage, since its curved geometry is critical to the cabinet's interference-free array behaviour. Verify which amplifier and processing rack is included or available separately.
