Kms symmetry xc(x) – Dayton Audio PS180-8 6-1 User Manual
Page 9
Bl(xb(x) + x) = Bl(xb(x) – x).
If the shift xb(x) is independent on the displacement amplitude x then the force factor asymmetry is caused by an offset of the
voice coil position and can be simply compensated.
If the optimal shift xb(x) varies with the displacement amplitude x then the force factor asymmetry is caused by an
asymmetrical geometry of the magnetic field and can not completely be compensated by coil shifting.
Kms Symmetry xc(x)
This curve shows the symmetry point in the nonlinear compliance curve where a negative and positive displacement x=xpeak
will produce the same compliance value
kms(xc(x) + x) = kms(xc(x) – x).
