A spider-less and suspension-less speaker system, having a diaphragm constrained to move in a linear direction and supported by a frictionless or low friction support. A voice coil coupled to an audio input drives the speaker diaphragm. A position sensor determines the physical position of the diaphragm. A control circuit uses the sensed position information to modify the audio signal in such a way that the interaction of the voice coil and the magnetic field both drives the diaphragm to produce an audible output and restores the diaphragm to a neutral position in the absence of a further audio signal.
