NEXO Introduces Compact GEO M10 Line Array
The new GEO M10 line array, unveiled at ISE is a high-output sound reinforcement
system for long-throw theatre and live music applications. This contemporary
design uses a single 10” driver to deliver an unprecedented ratio of LF response
to cabinet size for this class of mid-size line array.
The GEO M10 system is twice as more powerful as its sister GEO M6, launched two
years ago. While the M10 design aesthetic is comparable to the elegant new-generation
silhouette of the M6, the larger M10 cabinet draws on structural and acoustic
innovations first released in NEXO’s ground-breaking STM Series modular line array,
in particular the STM M28.
The M10 takes its name from the single 10” neodymium LF driver, paired with a 1.4” HF
titanium diaphragm HF driver. With a footprint of 531(W) x 288(H) x 355(D) mm, this
2-way passive module will deliver a frequency response of 59Hz-20kHz with nominal
peak SPL of 131dB.
There are two versions of the M10 cabinet, offering 12.5° and 25° of vertical dispersion.
Both have 80°/120° horizontal dispersion which can be configured manually, without
tools, by removing the magnetic grille and adjusting NEXO’s innovative flange fixing
system.
There are several advantages to the use of a single 10” driver, instead of the more
commonly found double-6” designs. The principle benefit is a much lower frequency
response from a 2-way cabinet. The box keeps a narrow profile, and its height provides
for tighter inter-cabinet angles.
As shown by the hugely popular GEO S8 compact line array, the single-driver design offers
better vertical control. NEXO’s proprietary Directivity/Phase Device (DPD) extends
upper line source coupling frequency limits between the adjacent 10” drivers, so the
adjacent loudspeakers couple as coherently as if there were twice as many 6” drivers,
mounted at half the physical distance.
Cabinet size has been a critical consideration for NEXO’s R&D engineers, guiding their
choice of components and enclosure materials, down to the lightweight neodymium driver.
In all, the M10 weighs just 21kg, and its impressively compact dimensions mean minimal
visual impact and improved sightlines, an important consideration for its target market
of theatres, auditoria and conferencing venues.
The GEO M10 is partnered by a dedicated sub-bass cabinet, the MSub15. Weighing 36kg, the
new sub is presented in a robust touring package with steel grille or in an elegant
installation version with cloth grille. It has large composite bumpers on each corner
and side handles. It flies with the M10 in an aesthetically pleasing and low profile
array, operable in omni or cardioid mode, as a result of its front and back connection
plates. The MSub15s are the same width as the M10 cabinets, but taller-two subs are
equivalent in height to three M10s.
M10 can be flown or ground-stacked, with or without the MSub15. Up to 12x M10 or 8x MSub15
modules can be combined in a single flown column, or, for instance, 3x MSub15s can be
arrayed above 9x M10 cabinets, using one of two dedicated bumper accessories.
Alternatively, the M10 elements can be ground-stacked on top of the MSub15s, with
between -12° to +12° of tilt.
