Abstract (en)
[origin: EP0350652A1] In such a loudspeaker having several loudspeaker units (13, 14, 15) which are connected to a frequency filter (3) via one power amplifier each (10, 11, 12), power amplifiers having a negative source impedance (-Ri) are proposed which reduce the linear and non-linear distortions to such an extent that the application of modern filters becomes possible and further measures for reducing non-linear distortions become applicable. <IMAGE>
