Electronics (D 7SUB)

Amplifier
The D 7SUB features a 400 Watt Class D amplifier that
operates at a highly efficient 85%. This means that 85%
of the power consumption is dedicated to the speaker,
and only 15% is dissipated as heat.
MFB (Motional Feed Back), servo control
We have given
precise timing
extremely
high priority in
the D 7
design. To
enable the
relatively
compact
subwoofer to
reach very low frequencies with perfect timing the D
7SUB features MFB.
