NEXO STM Series Speakers comprise of 4 proportionally-sized modules from which systems of any size and scale can be configured: M28 Omi-Purpose, M46 Main, B112 Bass and S118 Sub. Configuration possibilities include M28 Omni or M46 Main cabinets only, Omni/Main + Bass, Omni/Main + Sub, Omni/Main + Bass + Sub, any of which can be supplemented by the M28 Omni module operating as a downfill.
NEXO STM Series Speakers
For too long now, the business of a sound rental company has been dictated by system manufacturers. You need one type of system to be in the touring market, another for corporate jobs, and so on. It all adds up to a lot of boxes that often spend more time in the warehouse than they do on the road. STM changes all that.
The concept of Scale Through Modularity delivers a new level of versatility, enabling contractors to design a wide range of systems from just four compact, powerful and proportionally-sized modules. And in applications large and small, these systems can significantly outperform existing solutions.
Of course increased versatility brings a welcome improvement in return on investment. But with STM, that’s just the start. From system storage and configuration, through transportation and rigging, to wiring and amplification, STM delivers important operational and logistical cost savings at every stage of the process.
From a simple groundstack to a compact, powerful line array, STM makes it quick and easy to ‘clip together’ one, two or even three-wide systems to match any scale of job. Configuration possibilities include M28 Omni or M46 Main cabinets only, Omni/Main + Bass, Omni/Main + Sub, Omni/Main + Bass + Sub, any of which can be supplemented by the M28 Omni module operating as a downfill.
The wide operating frequency range of the M28 Omni cabinets means that many speech or light music events can be run effectively with M28 alone, thereby removing the need for any extra cabinets. If programme material calls for low frequency extension, the 25-120Hz range of the S118 sub and the 55-200Hz range of the B112 bass offer the user complete freedom when configuring the system to achieve the desired frequency response or power.
STM is all about flexibility, so there’s no such thing as a ‘typical system’. STM’s modular approach means there’s no longer a requirement to own separate small, medium and large systems as applications of any size and scale can now be handled from a common inventory of STM modules. Sharing the same footprint as the other STM modules, and precisely twice the height of the Main and Bass cabinets, the STM S118 Sub-Bass module also shares the same rigging system, allowing it to be groundstacked or flown above, below or between other STM modules.
Using a single 18″ driver in an innovative cabinet design, the S118 delivers performance levels comparable to NEXO’s acclaimed CD18 2 x 18″ sub, empowering the STM system with a compact, potent and highly musical sub-bass solution.
M28 Omni and M46 Main modules employ 2 x 8″ and 4 x 6.5″ long excursion drivers respectively in a symmetrical configuration. HF drivers use Keytone Polymer diaphragms to eliminate distortion up to 18kHz. Diagram 1 shows the M28 Omni Module.
The use of flat membrane MF drivers in the M46 Main Module allows the HF exiting between the baffles to expand uninterrupted, ensuring smooth frequency response and consistent horizontal coverage. Diagram 1 shows conventional HF diffraction using cone MF drivers, while Diagram 2 shows the smooth HF propagation along MF flat membrane drivers.
