That's the spirit! You got nuthin to lose. It needs to be organic wool, my friend, else it may change things for the worse. Happy trails, tho, with best wishes. I own a pair of Meridian M20 actives if that is somehow relevant and have fitted for several Epos models to include one ES-14.
Re: above, John Dunlavy also wrote "the output should equal the input". Amen. He wrote more about diffraction effects than anyone I know of and I do what he did. In fact, I modeled my patent application after his which expired in '99 using a good deal of his text. I've retro fitted for two Dunlavy model speaks down under, the wool was getting a little long in the tooth, with the same positive results. Who knows, that may be a cottage industry for me to come. Cheers.
