Power needed
30–120 W
per channel, into 4 ohms
To hit 95 dB peaks at 3 m from a pair of Elac Vela 2.0 VBS404.2-GB, you need at least 30 W a channel. More than 120 W is wasted here - that is all ELAC 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
- -82.0 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 87 dB, used as 82.0 dB per watt.
Eversolo AMP-F10 with the Elac Vela 2.0 VBS404.2-GB
Workable with care
10 dB of headroom over what this speaker needs - peaks stay clean. Well above the 120 W the maker rates the speaker for, so keep an eye on the volume knob.
Rated down to 2 ohms - stable into anything this speaker will throw at it.
Power rises usefully into 4 ohms (200 W to 320 W).
A power amplifier: you will need a preamplifier, or a streamer with a volume control, as well.

1
Excellent match
5 dB of headroom over what this speaker needs - peaks stay clean.
Has a 4 ohm tap, which is exactly what this 4 ohm speaker wants. Taps: 4 / 8 ohm.
A valve amplifier makes the same power on each tap, so what matters is sensitivity - and at 82.0 dB this speaker is efficient enough that 100 W is comfortable.
Balanced against the price of the speakers.

Workable with care
7 dB of headroom over what this speaker needs - peaks stay clean.
Rated to 4 ohms, but this speaker dips to 3.2. Fine at sane volume, tight if you push it hard.
Power nearly doubles into 4 ohms (70 W to 140 W) - a stiff supply that copes with hard loads.
Balanced against the price of the speakers.

Showing the best 20 of 191. Narrow it with the price range below, or a different budget split.
46 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.

Thanks - noted.
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 Elac Vela 2.0 VBS404.2-GB specs.
