The Phonogen was the hobby horse of Mr. Nobert Schäfer, at that time based in Beuron. The basic principle was the specially made exponential horn, which was cast from lightweight concrete. The entire exponential curve is rounded to avoid standing waves. Common technical data: - Weight min.73 kg - Dimensions W x H x D 60 cm x 80 cm (120 reference) x 70 cm - Frequency response 18 - 25000 Hz (40 kHz reference) - Efficiency approx. 100 dB at 1 W at 1 m distance They were available in at least three versions: 1stversion: - passive with dynamic loudspeakers - active two-way frequency crossover - price approx. 8000,- DM - Weight 73 kg - dimensions W x H x D 73.5 cm x 100 cm x 59.5 cm 2ndversion: - passive with magnetostats in the mid-high frequency range - active two-way frequency crossover - price approx. 10000,- DM 3rd version 1A: later selected as a "reference" in cooperation with the magazine Audio - 3 ways fully active - 3 Backes and Müller amplifiers (2 x bass direct / exponential) each with active feedback - 2 Backes midrange and Müller tube amplifiers with ion tweeter from Audiotrade, now Acapella Price 25000,- DM More information at the following homepage: http://www.plasmatweeter.de/phonogen.htm Unfortunately, the speakers were only built for a short time, because there were extreme problems with the ion tweeter in particular. The return was just too high. Mr. Schäfer then canceled the project and founded a new company: it is called Translife , these boxes are realized with surface spotlights, where he discovered interesting things about the sound propagation. Just take a look at http://www.translife.de Furthermore, he was one of the first to dare to build a digital power amplifier next to Sony . In line with the Phonogen , he has developed the Phonogen Digital 1000 digital power amplifier. The successor was then the Phonogen Digital 2000, which was rated very well at "Audio". He has also developed a timer.
