Average
Median

Nominal Impedance of the 4 Ohms means that the MartinLogan Foundation F1 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 Foundation F1 with an AVR but use an Integrated Amplifier instead.

Sensitivity

92dB of the MartinLogan Foundation F1 is considered a high sensitivity compared to average stereo speaker which makes Foundation F1 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 Foundation F1 will be a good choice.

  • Speaker Cable and Connectors
    • Speaker Cables with Banana Plugs: If you know the lenght of the cable you need, this is the easier option to connect your speakers with your amp.
    • Speaker Cables without Connectors: If you are not sure about the lenght or need longer than standard cables with plugs, choose this option.
    • Banana Connectors and Plugs: If you chose the cables without connectors option or already have some cable around, pick the banana plugs separately.
