[Feature] An interesting approach to MEMS loudspeaker design delivers surprisingly good results from a balanced radiator, and "omni" loudspeakers made up of multiple drivers on the surface of a sphere can be modelled in such a way as to understand their likely directivity response. We find that limiting the overall energy stored in a loudspeaker system may prove more effective as a means of control than conventional voltage limiting. Finally there is clearly still considerable interest in research on flat panel loudspeakers, and some evidence that timbral uniformity across listening locations may be improved when using these.
