Die Back-Uhr (alle Ziffern sequentiell auf einer 7-Segment-Anzeige)

An earlier article explained the operating principle of the electronic loudspeaker. It was shown that this approach enables a woofer in a relatively small enclosure to provide really good reproduction quality from 40 Hz upwards. The second step is to describe a complete system, using active crossover networks, based upon the electronic loudspeaker used as a woofer. The system provides unusually good reproduction quality for its modest size and low cost.
