Power needed
6.3–100 W
per channel, into 6 ohms
To hit 95 dB peaks at 3 m from a pair of Q Acoustics 3090c, you need at least 6.3 W a channel. Anything from about 13 W to 100 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
- -88.8 dB effective sensitivity
- 1.2 dB taken off to convert the 6 ohm 2.83V rating to dB per watt
- 2 dB allowed for optimistic published sensitivity
- Published sensitivity 92 dB, used as 88.8 dB per watt.

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 Q Acoustics 3090c specs.
