Power needed
19–25 W
per channel, into 4 ohms
To hit 95 dB peaks at 3 m from a pair of Wilson Audio WATT/Puppy, you need at least 19 W a channel. More than 25 W is wasted here - that is all Wilson Audio 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
- -84.0 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 89 dB, used as 84.0 dB per watt.
Rega io with the Wilson Audio WATT/Puppy
Workable with care
2 dB of headroom over what this speaker needs - peaks stay clean.
Rated to 4 ohms, but this speaker dips to 2.87. Fine at sane volume, tight if you push it hard.
No 4 ohm power rating on file. On a 4 ohm speaker dipping to 2.87 that is the figure that matters, so this one is unproven on the load.

3 dB of headroom over what this speaker needs - peaks stay clean. Well above the 25 W the maker rates the speaker for, so keep an eye on the volume knob.
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 84.0 dB this speaker is efficient enough that 42 W is comfortable.
Well below the speakers - leaves money on the table, but nothing wrong with it.

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.

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 Wilson Audio WATT/Puppy specs.
