conventional systems
The
SF-30A
makes use of an innovative and
unique transducer based on the patented M-
Force® moving magnet linear motor structure.
Unparalleled performance in terms of power
handling, electromagnetic conversion, reliability
and maximum SPL are a few of the innovative
features and improvements with respect to the
conventional moving coil arrangement.
The motor system is driven by an ultra high
power Class D amplifier module which is no less
impressive than the motor design. Amazing figures
in terms of both output voltage (310 Vpeak) and
current capabilities (200 Apeak), the M-Drive®
amplifier is capable of exploiting the full potential of
the M-Force®. The DPC® (Differential Pressure
Control) is a powerful active acoustic processing
tool which controls and enhances the performance
of the system.
