Most of loudspeaker power ratings I'm familiar with are rated using the EIA 426A noise source, pink noise with a 6 dB crest factor, or "RMS" power, (presumably) sine wave power with a 3 dB crest factor.
Recently have seen the IEC 2685 18.1 power rating used, but have not been able to find what the source is, any references?

AFAIK IEC 268-5 defines a pink noise soure with a crest factor of 6 dB which is bandwidth limited by two 2nd order Butterworth filters at 40 Hz and 5 kHz.

Thanks for the link to the JBL paper. Just try looking up what the IEC standard is and all you get is their website saying you have to pay just to see the glimpse of the standard. I am sure there are more things to the protocol for testing but it sure was helpful just to get one sentence of pink noise band limited at 40Hz and 5kHz by BW2 filters.
