         Nominal Impedance of the 4 Ohms means that the ELAC Uni-Fi UB5 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 ELAC Uni-Fi UB5 with an AVR but use an Integrated Amplifier instead.
 Sensitivity
 With a sensitivity level of only 85 dB, ELAC Uni-Fi UB5 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 amps.
