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.
From a simple groundstack to a compact, powerful
line array, STM makes it quick and easy to ‘clip
together’ the systems you need for any job.
Configuration possibilities include Main cabinets only,
Main + Bass, Main + Sub, Main + Bass + Sub. The
wide operating frequency range of the M46 main
cabinets means that many speech or light music
events can be run effectively with M46 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.
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.
Innovative PistonRig™ and REDLock™ rigging enables
any size of system to be flown safely by one person.
PistonRig™ allows pre-setting of inter-cabinet angle
values. REDLock™ handle locks front rigging points
from rear of cabinet. All adjustments made from one
position at rear of cluster.
