Скачать или смотреть Celestion Greenback Cone Breaking Test nagrywamy.com

Is cone breaking or speaker distortion a fact or a myth? Let's check. I've recorded a vintage Celestion Greenback speaker in open box powered with a solid state power amp at full power, about 30W, and then at 1/100 of rated power, ie about 300mW.
A guitar track comes from http://www.cambridge-mt.com/ms-mtk.htm and it's a piece of guitar part of Hollow Ground's „Left Blind”.
While checking real levels I found that there is not 20dB but 19,6dB difference - so you have to set it right while comparing. I don't know if this difference is from the amp or the speaker, but there is difference in level about 0.4dB.
