Power needed
95–120 W
per channel, into 4 ohms
To hit 95 dB peaks at 3 m from a pair of Emotiva Airmotiv XB1, you need at least 95 W a channel. More than 120 W is wasted here - that is all Emotiva 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
- -77.0 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 82 dB, used as 77.0 dB per watt.
Marantz Stereo 70s with the Emotiva Airmotiv XB1
Workable with care
Just barely enough (2 dB of headroom). Fine at normal volume, no reserve for peaks.
Rated down to 4 ohms, comfortable with a 4 ohm speaker.
Power nearly doubles into 4 ohms (75 W to 150 W) - a stiff supply that copes with hard loads.

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 Emotiva Airmotiv XB1 specs.
