NEXO Introduces Alpha + at ISE 2025 for Modern Venues
NEXO's Alpha + integrates advanced technologies to deliver enhanced performance and flexibility
NEXO has introduced the Alpha + at ISE Barcelona, February 2025 a hybrid source
sound reinforcement
system designed to modernise and optimise large-scale point source audio for a range of
applications, including live music venues, nightclubs, theatres, sports arenas, and concert halls.
Inspired by the original Alpha Series from the 1990's, Alpha + integrates advanced technologies to
deliver enhanced performance and flexibility.
The original Alpha Series was recognised for revolutionising sound reinforcement with its innovative
point source approach, designed for mid to large-scale front-of-house (FOH) applications. The new
Alpha + maintains this core philosophy while incorporating modern advancements that enable superior
sound control and ease of deployment.
The Alpha + system consists of three primary components:
- M210 Main Module: A horn-loaded 2 x 10" enclosure with 4 x 3" high-frequency (HF)
compression drivers.
- B218 Bass Module: A horn-loaded 2 x 18" enclosure.
- L20 Sub-bass Module: A band-pass 1 x 20" subwoofer adapted from the NEXO P+ Series.
The modular nature of Alpha + allows for flexible configurations, with Main and Bass modules
typically paired at a 1:1 ratio. The system can be rapidly stacked, making it a practical choice for
venues requiring high-output sound reinforcement without the complexities of flying line arrays.
One of Alpha +'s defining features is its ability to modify horizontal directivity. The continuously
varying dispersion pattern shifts from 60° at the top of the M210 Main Module to 120° at the bottom.
This can be further adjusted to 90°/120° or 60°/60° using interchangeable flanges. Additionally, the
waveguide block can be adjusted from a Narrow vertical coverage (0°/-20°) to Wide/Standard
(+20°/-20°) setting, providing a high degree of customisation.
This precise control over dispersion characteristics brings many benefits traditionally associated
with line array coupling while retaining the simplicity and ease of deployment of point source
systems. NEXO refers to this configuration as Hybrid Source technology.
To power the Alpha + system, NEXO recommends the NXAMP4X4Mk2 Powered TD Controller, a 4 x
4500W (2
Ohms) amplifier with advanced processing capabilities. A standard stacked configuration comprising
one M210, one B218, and two L20 modules per side requires only a single NXAMP4X4Mk2 per
channel
distribution:
- Two channels for the Main Module
- One channel for the Bass Module
- One channel for both Sub-bass Modules
Alpha + is designed to accommodate a variety of environments. Gareth Collyer, NEXO Sales and
Marketing Director, highlights its adaptability: "Like its predecessor, Alpha + is an impressively
powerful system, with new features that make a lot of sense in the modern world."
He further explains the benefits of Alpha + in mid-sized festival settings, stating: "A stacked
system that can handle a mid-sized festival stage saves a lot of cost building towers and flying
line arrays, and Alpha + goes where a line array won't, such as theatres and venues without hanging
points."
Additionally, Collyer emphasises Alpha +'s appeal for nightclubs, referencing its heritage: "And all
the club-goers around the world who've enjoyed a great night on an Alpha-powered dancefloor are in
for a real treat when they hear Alpha +."
With Alpha +, NEXO has redefined its approach to point source sound reinforcement, offering a hybrid
system that bridges the gap between traditional FOH solutions and modern line array technology. By
retaining the powerful, high-output characteristics of the original Alpha Series while integrating
advanced dispersion control and flexible configuration options, Alpha + presents a compelling
solution for venues seeking state-of-the-art sound reinforcement with practical deployment
advantages. The system's modular design, combined with high-efficiency amplification, makes it a
robust choice for live events, theatres, concert halls, and nightclubs looking to enhance their
audio experience with cutting-edge performance.
