Nominal Impedance of the 4 Ohms means that the Sonus Faber Sonetto II is a difficult to drive speaker from nominal Impedance perspective, make sure that you choose an amplifier than can provide 4 Ohms for this speaker.
Many AVRs (audio/video receiver) in the market may have difficulty when the speakers dip below the 4 Ohms levels (this may cause clipping or even physical damage), so we recommend to not pair the Sonus Faber Sonetto II with an AVR but use an Integrated Amplifier instead.

With a sensitivity level of only 87 dB, Sonus Faber Sonetto II is a difficult to drive speaker from Sensitivity perspective, make sure to choose an amplifier with a high output if you like listening to your music at high volume levels.
