, and has a sensitivity of 87 dB
Nominal Impedance of 4 Ohms means that the KEF R3 Meta 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 KEF R3 Meta with an AVR but use an Integrated Amplifier instead.
With a sensitivity level of only 87 dB, KEF R3 Meta 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.
