The loudspeaker was developed by Bernd Timmermanns. The crossover consists of a blocking circuit for mid-range reduction. The frequency response is balanced. The decay spectrum (waterfall diagram) is exemplary for a broadband loudspeaker. It shows a rapid decay of all resonances. The non-linear distortions are less than 1% above 100 Hz at 90 dB (1m) sound pressure.
