ABSTRACT:
The loudspeaker system uses an inner transducer for pressure control in the closed loudspeaker housing to simulate the desired baffle properties. The speed of the membrane of the inner transducer is either proportional to the derivative of the pressure, or proportional to the intergral of pressure changes, or comprises summands proportional to the pressure, to the pressure's derivative and to the pressure's intergral.
