Newport Test Labs reported that as a result of its extensive objective testing, it would put the frequency response of the Sonus faber Electa Amator III loudspeakers as 59Hz to 32kHz ±3dB, which is an excellent result both in terms of overall linearity and extension at both ends of the audio spectrum.
The frequency response depicted in Graph 1 is a composite, where the low-frequency in-room response (from Graph 5) has been spliced (at 600Hz) to the gated (anechoic) high-frequency response
