Some pictures of custom fitted examples can be see in the Classified section 10/07. The so called wool products to be found in fabric and hardware stores are composed largely of synthetic materials that are themselves reflective. The pads under discussion from diffractionbegone.com are made from natural wool in the necessary depth and density. Short and spreading waveforms that would otherwise be reflected (diffracted) by naked baffles and cabinet edges and late arriving make contact with the wool instead and are absorbed. What a user gets at the listening position is purer and unadulterated information.
FYI, when diffracted waveforms sum in at the listening position, they combine to cause a bump and ripples to frequency linearity in the lower bandpass of tweeters. Not only is proper time and phase preserved, so is frequency response.
