4 : 3.Plug the motor to the amplifier
Take care to match the polarity while plugging the ampli-
fier 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 ac-
cepts a 10 mm, 1 ROW, 4P housing.
Crimp the terminal on the wire securely and install the
terminals in the housing.
4 : 4.Verify the alignment of the diaphragm
Place the diaphragm into the cabinet and take care that
it fits the baffle cutout and perfectly lies on its the surface.
No room must be left between the diaphragm an the surface
in order to properly center and fix it.
Placing a neoprene foam in between the diaphragm and
the cabinet ensures good sealing and prevent air leakage.
Do not fasten the diaphragm to the
cabinet before having fitted and perfectly
aligned its vertex to the motor’s hub.
Misalignments could bring forth system instability, dis-
tortions and possibly damages.
The exact matching between the diaphragm and the
M-Force’s hub shall guarantee no tensions and displace-
ments at the rest position of the system.
