STM Series

Finally, a system that works the way you work.

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 core modules. And in applications large and small, these systems can significantly outperform existing solutions.From a simple ground stack to a massive stadium system, STM makes it quick and easy to 'clip together' the systems you need for any job. One day it could be for an event audience of 1000. The next day for 100,000. STM can be flown one wide, two wide or three wide on a single bumper. The facility to add a third hang of Bass modules creates a system of unrivalled power with massive LF headroom.In developing STM, NEXO considered not only the versatility and performance of the system in use, but also its efficiency of operation at every stage of the live sound rental process. Modular dollies, road-ready casing and universal amp racks deliver significant savings in operational costs, further enhancing return on investment. Innovative PistonRig™ and REDLock™ rigging enables any size of system to be flown safely by one person. Using a compression-mode rigging method, the system remains completely flat during rigging, and requires no lifting or pushing.

STM M46

Injection-moulded high-power cabinet with innovative components for enhanced performance. Flat-membrane drivers ensure completely even and full-range coverage over entire 90° horizontal dispersion. HF frequency range remains completely linear, using Ketone Polymer diaphragms that enhance tonal response and long throw.

  • 4 x 6.5 inch LF/MF Drivers
  • 4 x HF Compression Drivers
  • 145dB peak SPL
  • Frequency response: 85Hz-20kHz
  • H350mm/W575mm/D715mm
  • 55Kg/121lb
  • Dispersion 90° H x 0-10°V

STM B112

Injection-moulded bass cabinet featuring a Neodymium high excursion 3000W 12" bass driver with 4" voice coil. It has the same format — dimensions,weight, gravity centre — as the M46. The hybrid horn-loaded design maximizes the efficiency of the driver, delivering 6dB more than a standard front-loaded driver in this frequency range.

  • 1 x 3000W +/- 3cm excursion 12 inch LF Driver
  • 141dB peak SPL
  • Frequency response: 63Hz-200Hz
  • H350mm/W575mm/D715mm
  • 59Kg/130lb

STM S118

Sub-bass cabinet featuring a Neodymium high excursion 3000W18" driver. A bandpass load ensures SPL output equivalent to conventional dual 18" sub-basses. Same width, double the height of M46 main cabinet, double height of main cabinet so the S118 can be flown in the array or ground-stacked in line. Can be run in omnidirectional or cardioid sub mode.

  • 1 x 18 inch LF Driver
  • 143dB peak SPL
  • Frequency response: 25Hz-85Hz
  • H700mm/W575mm/D715mm
  • 85Kg/187lb
  • Omni or cardioid modes

STM M28

Injection-moulded all-purpose loudspeaker cabinet which fulfils the role of downfill, providing 90° or 120° of horizontal dispersion and 0° to 15° splaying angle between modules. Same width as M46, 2/3 height, the M28 can also be used independently from M46 or B112.

  • 2 x 8 inch LF Drivers
  • 2 x HF Compression Driver
  • 141dB peak SPL
  • Frequency response: 60Hz-20kHz
  • H233mm/W575mm/D650mm
  • 37Kg/82lb
