Unlike electronics where the distortion is in the 0.0x% range, distortion in speakers can go up to 5%,10%,20% or even higher, particularly at the low frequencies. That's why speaker manufacturers do not generally publish distortion data, unlike electronics makers.
Canada's NRC has generated accurate data on thousands of speakers, but manufacturers rarely publish them. I applaud soundstage.com for having these speakers tested at NRC and publishing the results, which will undoubtedly benefit the consumer.
