After the Descartes (I), his first masterpiece, Dennis Frank developed the Descartes II. His goal was to produce a loudspeaker with an extremely high efficiency. For this the Alcone AC 15 with 94 dB (2.83V/1m) is just the right thing.
The two Alcone AC 6.5 HE also reach the required efficiency. Since this driver does an excellent job in a speaker like the Pascal, it was the natural choice for the Descartes II.
There was still the question which bass driver should be used: sure, there are quite a few that have an efficiency of 94 dB, but then the cabinet might get too big or there is not enough low bass. Dennis Frank chose a different way. The bass had to be active. Two Alcone AC 8 HE are the perfect solution.
The Descartes II shows the following characteristics:
