ABSTRACT:
In a loudspeaker with a number of speaker units, each connected across one power amplifier to a diplexer, the power amplifiers having negative source impedance (-R.sub.1) are utilized. The diplexer includes an adder circuit and a filter connected thereto. The power amplifiers with negative source impedance reduce the linear distortions to such an extent that the use of modern diplexers is possible and further measures for reducing nonlinear distortions are appropriate.
