Sensitivity
Center Channel Speakers
Nominal Impedance of 4 Ohms means that the Sonus Faber Lumina Center I 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 Lumina Center I with an AVR but use an Integrated Amplifier instead.
Sensitivity
With a sensitivity level of only 87 dB, Sonus Faber Lumina Center I 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. You may especially have a hard time using Tube amplifiers which are traditionally very low power compared to Class A/B or Class D speakers.
