Nominal Impedance of 4 Ohms means that the KEF Reference 1 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 Reference 1 Meta with an AVR but use an Integrated Amplifier instead.

Sensitivity

With a sensitivity level of only 85 dB, KEF Reference 1 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. 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.

Minimum Impedance of KEF Reference 1 Meta

Even though the nominal impedance of the Reference 1 Meta is 4 ohms, the minimum impedance level of this speaker according to KEF is 3.2 ohms KEF Reference 1 Meta so while choosing an amplifier, you should ideally check if the unit you are considering can provide this impedance level.

Input Type
