ABSTRACT:
In order to obtain for electrodynamic loudspeakers, on the one hand, the energy-favorable acoustical enhancement by the bass reflex principle and, on the other hand, to be able to use the motional control of the diaphragm of the electrodynamic loudspeaker by controlling such by means of an amplifier exhibiting negative output impedance, it is proposed to compensate the thus resulting unfavorable frequency characteristic by a forwardly connected circuit which generates an inverse characteristic with respect to the unfavorable frequency characteristic.
