Audaphon Facette AM floorstanding loudspeaker from Hobby Hifi 4/2017

Kit without housing, price per speaker

Facette AM is a two-way floorstanding loudspeaker. Facette AM is a bass reflex loudspeaker. Facette AM is a high-quality loudspeaker with chassis from Audaphon and Wavecor, in which a passive membrane guarantees deep bass for bass tuning. The loudspeaker contains the following loudspeaker chassis: - an Air-Motion-Transformer AMT 1i - a woofer WF182CU12 The loudspeaker was developed by Bernd Timmermanns. The crossover consists of: - a 2nd order high pass (12 dB / octave) for the tweeter. - a 3rd order low pass (18 dB / octave) for the woofer. The frequency response of the loudspeaker is perfectly linear. The decay spectrum (waterfall diagram) is exemplary without any disturbing resonance. The non-linear distortions are extremely low at 90 dB (1m) sound pressure: they are less than 0.3% above 500 Hz. That is absolutely outstanding.
