FA5.3 - Measurement diagrams
The up-to-date measurement diagrams of the FA5.3 :
These graphs demonstrate the step response (left graph), the impedance response and the electrical phase
response (right graph). We are especially proud of the perfect step response as measurement proof of
the time-coherent reproduction of our loudspeakers. This is why they bring the music so close to you.
The realization of the linear impedance behaviour of a loudspeaker (right graph) ensures that with
this loudspeaker the amplifier sees the same load in all frequency ranges (impedance = frequency-dependent
resistance), whereby a harmonic sound reproduction is achieved. All loudspeakers from FÖRSTER AUDIOTECHNIK
show linear impedance behaviour. Due to their impedance behaviour, among other things, they are ideally
suited for all amplifiers, even for tube amplifiers.

Time coherence
The step response as acid test: Why our chassis operate time-coherently and are team players.
Innovation
The future: the complete digital-analogue system. Supported by the Free State of Bavaria.
Low distortion
It is essential for natural sound reproduction that the sound is not distorted.
