Power needed
7.5–120 W
per channel, into 8 ohms
To hit 95 dB peaks at 3 m from a pair of Focal Theva No2, you need at least 7.5 W a channel. Anything from about 15 W to 120 W a channel is comfortable; past that, more watts stop buying you anything.

68 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 Focal Theva No2 specs.
