Nominal Impedance of the 4 Ohms means that the MartinLogan Motion SLM 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 MartinLogan Motion SLM with an AVR but use an Integrated Amplifier instead.

94dB of the MartinLogan Motion SLM is considered a high sensitivity compared to average stereo speaker which makes Motion SLM an easy to drive from Sensitivity perspective. If you are planning to power your speaker with a Tube amp which are generally very low power, the MartinLogan Motion SLM will be a good choice.
