Nominal Impedance of the 4 Ohms means that the Focal Sib-T 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 Focal Sib-T with an AVR but use an Integrated Amplifier instead.

90dB of the Focal Sib-T is an average sensitivity for stereo speaker so it is neither easy nor difficult to drive Sensitivity wise.

      • Speaker Cables without Connectors: If you are not sure about the lenght or need longer than standard cables with plugs, choose this option.

    • Acoustic Panels and Treatments: Your room is as important as your stereo equipment so acoustic treatments goes a long way in improving the overall performance.
