I beg to differ a bit....
the Confidence C1 are spec'd at 85dB/2.83V/1m, 4 Ohms.
so. really that's 2W into the speaker once you do the math. To normalize that to another 8 Ohm speaker, we will have to half the input power (down to 1W). This means that the sensitivity will drop 3dB.
So, the Confidence C1 are actually 82dB/1W/1m, 4 Ohms.
You can use this number as a direct comparison to the KEF Ref 1 (which is spec'd correctly since it's an 8 ohms speaker).
You have a 3dB difference in sensitivity bwtn these speakers. It might all work out just fine for you but Keep that in mind when you decide.
