Power needed
9.5–150 W
per channel, into 4 ohms
To hit 95 dB peaks at 3 m from a pair of MartinLogan Motion F20, you need at least 9.5 W a channel. Anything from about 19 W to 150 W a channel is comfortable; past that, more watts stop buying you anything.

- 95 dB target at the seat
- +4.8 dB for 3.0 m of distance
- -3 dB for a stereo pair
- -87.0 dB effective sensitivity
- 3.0 dB taken off to convert the 4 ohm 2.83V rating to dB per watt
- 2 dB allowed for optimistic published sensitivity
- Published sensitivity 92 dB, used as 87.0 dB per watt.
Advance Paris X-A220 EVO with the MartinLogan Motion F20
Good match
14 dB of headroom, far more than needed. No harm in it.
Rated down to 4 ohms, comfortable with a 4 ohm speaker.
No 4 ohm power rating on file. On a 4 ohm speaker that is the figure that matters, so this one is unproven on the load.
A power amplifier: you will need a preamplifier, or a streamer with a volume control, as well.

Listed separately because they are not a complete system: a power amplifier has no volume control and no inputs to speak of, so you need a preamplifier or a streaming preamp as well. Worth it if you already own one, or if you want to buy the two halves separately.

Sensitivity and impedance figures are the manufacturer's own. We read sensitivity as dB at 2.83 V/1 m and take 2 dB off it, because published figures run high. Treat the result as a well-founded starting point, not a measurement. Full MartinLogan Motion F20 specs.
