Power needed
15–100 W
per channel, into 5 ohms
To hit 95 dB peaks at 3 m from a pair of MartinLogan Foundation B1, you need at least 15 W a channel. More than 100 W is wasted here — that is all MartinLogan rates the speaker to take.
Show the working
- 95 dB target at the seat
- +4.8 dB for 3.0 m of distance
- -3 dB for a stereo pair
- -85.0 dB effective sensitivity
- 2.0 dB taken off to convert the 5 ohm 2.83V rating to dB per watt
- 2 dB allowed for optimistic published sensitivity
- Published sensitivity 89 dB, used as 85.0 dB per watt.
Advance Paris X-A160 EVO with the MartinLogan Foundation B1
Workable with care
10 dB of headroom over what this speaker needs - peaks stay clean. Well above the 100 W the maker rates the speaker for, so keep an eye on the volume knob.
Rated down to 4 ohms, comfortable with a 5 ohm speaker.
No 4 ohm power rating on file, so we cannot judge current delivery.
A power amplifier: you will need a preamplifier, or a streamer with a volume control, as well.

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 Foundation B1 specs.
