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 3050, you need at least 6.3 W a channel. More than 100 W is wasted here — that is all Q Acoustics 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
- -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.
Marantz MM7025 with the Q Acoustics 3050
Good match
13 dB of headroom, far more than needed. No harm in it.
Rated down to 6 ohms, comfortable with a 6 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.

Showing the best 20 of 189. Narrow it with the price range below, or a different budget split.
47 power amplifiers that would also drive them
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 3050 specs.
