What "spec" we're they quoting at 2dB?
Agreed.

Here is their A/B test video using a SPL meter. They did not test with pink or white noise. They measured 2.2dB and believe that is twice as loud versus twice the power. I sent them the following dB/voltage/power/loudness chart and they told me the chart was incorrect.
