Nexo has released the Geo-M10 mid-size line array, a high-output sound reinforcement system for long-throw theatre and live music applications, promising ‘an unprecedented ratio of LF response to cabinet size’ from a single 10-inch driver.
The Geo-M10 system is twice as 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 STM Series modular line array, in particular the STM M28.
The M10 name refelects the single 10-inch neodymium LF driver, which is paired with a 1.4-inch titanium diaphragm HF driver. With a footprint of 531mm (W) x 288mm (H) x 355mm (D), this two-way passive module offers 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 flange fixing system.
Nexo claims several advantages to the use of a single 10-inch driver, instead of the more common double-6-inch configuration. The principle benefit being a lower frequency response from a two-way cabinet. The box keeps a narrow profile, and its height provides for tighter inter-cabinet angles.
A single-driver design also offers better vertical control. Nexo’s proprietary Directivity/Phase Device (DPD) extends upper line source coupling frequency limits between the adjacent 10-inch drivers, so the adjacent loudspeakers couple as coherently as if there were twice as many 6-inch 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 21kg, and its 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 subbass cabinet, the MSub15. Weighing 36kg, this is available in a robust touring package with steel grille or an installation version with cloth grille. It has large composite bumpers on each corner, and side handles. It flies with the M10 in a low-profile array, operable in omni or cardioid mode, thanks to 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.
The M10 can be flown or groundstacked, with or without the MSub15. Up to 12 M10 or eight MSub15 modules can be combined in a single flown column, or, for instance, three MSub15s can be arrayed above nine 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.
The rigging system for the Geo-M10 evolves another step from the original designs in the Geo-M6 and the STM Series. The internal three-point rigging system now features automatic locking and no loose parts. Two different bumper options are available, both with optional expansion bar, as well as an extension accessory for groundstacking.
Highly cost-effective amplification is via Nexo’s NXAmp4x4 TDcontroller; with up to four M10 cabinets per channel, and up to three subs per channel, the system can be controlled over a network using a Dante, Ethersound or AES/EBU digital expansion card.
Available in black and white, touring and installation cabinet versions as standard, M10 can also be ordered in the full range of RAL colour options. It has full TUV certification.
