2 : 1.Welcome
Congratulations on your purchase of the Powersoft
M-Force 301P01.
We know you are eager to use M-Force 301P01, but
please take a moment to read this guide, the safety instructions and Section: Important notes (p. 6) . In case you
have any questions, please do not hesitate to contact your
dealer or Powersoft.
M-Force is an innovative and unique transducer based
on a patented moving magnet linear motor structure.
The M-Force 301P01 is delivered as a factory matched
motor and diaphragm assembly aimed to simplify the cabinet building procedure. The mounting braket also aids in
thermal dissipation.
Unbelievable performance in terms of power handling,
electromagnetic conversion, reliability and maximum SPL
are a few of the incredible features and improvements with
respect to conventional moving coil arrangement.
The M-Force 301P01 is a true paradigm shift from the
old and fashionable coil and cone. Unlike conventional
loudspeakers M-Force’s moving magnet motor is a genuine
push-pull motor where magnetic elds interactions guarantee linearity in power requirement versus moving element
displacement. This, coupled to the the fact that no electical
conductors are present in the motor’s moving parts, brings
forth high efciency of the transducer: the moving magnet
linear motor ensures high force factor yielding negligible
power compression and very low input impedance.
With respect to conventional loudspeakers, M-Force
drives less power from the amplier to reach high audio performance, high SPL and low distortion; robust and reliable,
its performance withstand years of abuse and operation.
M-Force has been designed with an eye to the environment: high power efciency, high thermal inertia, low usage
of Neodymium (at equal SPL in comparison to conventional
design) are distinctive features of the Powersoft’s Green
Audio philosophy.
2 : 2.Unpacking & checking for shipping damage
Your Powersoft product has been completely tested and
inspected before leaving the factory. Carefully inspect the
shipping package before opening it, and then immediately
inspect your new product. If you nd any damage notify the
shipping company immediately.
The M-Force package contains one motor and diaphagm
assembly, a s the parts listed in TA B LE 1.

4 : 2.Plug the motor to the amplifier
Take care to match the polarity while plugging the amplier to the M-Force. Ensure that engine polarity matches the
DPC sensor position within the cabinet (refer to the M-Drive
User Guide for more in-depth information).
Polarity mismatch may lead to phase cancellation in
multiway systems, yielding to a wrong frequency response
and poor performances. If reversing the signal polarity is
needed when alighning the cabinets to the system, do it via
DSP, before the amp stage.
The four poles connector on the connector plate accepts a 10 mm, 1 ROW, 4P housing.
Crimp the terminal on the wire securely and install the
terminals in the housing.
Installation instructions
4
Once the cabinet has been realized, its time to mate it to
the M-Force 301P01.
This can be accomplished in 2 steps:
1. Unsecrew the M6 nuts with a 10 mm wrench, and a
TX30 M6x40 Torx screwdriver. (check FIGURE 1)
2. Use the same screws and nuts to mount the M-Force
301P01 to the cabinet.
4 : 1.Support braces.
When mounted to an adequately solid surface, the
M-Force 301P01 is completely self- supporting. However,
since the forces at play are signigicant, in order to enhance
the cabinet’s rigidity it is possible to easily fabricate some
support brackets to attach the motor to the side panels of
the cabinet.
Quotes for the anchor points can be found on FIGURE 3.

Important notes

5 : 1.Preset HPF
In order to avoid damages to the mobile equipment, we
recommend to set a 15 Hz (at least) High Pass Filter on the
input signal path.
Since the M-Force 301P01 is characterized by a very
low load impedance, any unwanted DC or low-end content
would pass through the motor to the diaphragm: without an
input HPF this would cause damages to the moving parts.
5 : 2.No mechanical load
It is highly recommended to limit motor excitation when
the same is not properly connected to a mechanical load.
5 : 3.Screws tightening torque
We recommend to use a torqued screwdriver in order to
apply the proper 15 N/m tightening torque.
5 : 4.Rim and baffle cutout diameters
The bafe cutout is 717 ± 1 mm.
In order to avoid mechanical interference and provide
the right tightening force to the diaphragm, respect the
tolerance for the internal diameter of the rim and the bafe.
Rounding off the edge of the cut drastically reduces the
stress of the components.
5 : 5.Thermal considerations
The M-Force 301P01 is characterized by high thermal inerthia.This results in a slower variation of the body
temperature during normal operation: the motor appears
to stay at low temperature for long time (expecially during
benchmark tests), but after hours of operation, the system
may reach very high temperatures, making the heat transfer
to the surrounding environment an issue.
As any other traditional transducer, it is highly recommended to favor the ventilation of the motor of the M-Force
301P01, taking advantage of the air ow by the diaphragm
and/or exploiting the ventilation offered by the ducts of the
cabinet.
When achievable, take into account congurations
where the motor is positioned outside the cabinet.
Powersoft recommends to mount the M-Force
301P01 in a well ventilated position.
5 : 6.Mechanical strength of the cabinet
The M-Force 301P01 is capable of producing very high
static and dynamic mechanical stresses to the cabinet. Two
main effect must be taken into account:
the internal sound pressure produced by the
movement of the diaphragm can rise up to 100 g/ cm2
(9,8 kPa - 204,8 psf): this pressure dynamically
stresses the cabinet boundaries;
the anchor points of the bafe, where the motor and
diaphragm assembly is mated with the cabinet, are
the most highly stressed part of the cabinet. Take
into account to strengthen the overall structure and
think about adding a support bracket as described in
section 4.1, Support Braces.
5 : 7.Mechanical balancing
The design of the cabinet shall take into account the
dynamic balancing of the center of mass of the M-Force
301P01 and diaphragm assembly.
Stating the high moving mass it is very important to
place the (moving) center of mass of the M-Force 301P01
as close as possible to the (static) center of mass of the
cabinet. This will reduce vibration and torque that make the
cabinet instable.
5 : 8.Acoustic load balancing
The diaphragm is subjected to high acoustic load. In
order to limit cone rocking it is highly recommended to
design the system so that the diaphragm is symmetrically
acoustic loaded.
