Hear ya go George if you can understand this read..
Jon Dahlquist was the speaker designer Debbie Miles my seismologist friend coined the phrase interfering energy as we both have designed products that reduce a polarity of shear.
Shear does return to the source and therefore generates interference. Shear is how a speaker works.Some energy moves straight off the center of the cone or membrane. The rest moves on both sides and thru the cone..and guess watt it hits the surround and the frame and returns back down the cone and interferes with the note that's coming its way. And it also bounces off the dust cap.. A head on collision...same goes for your audio room. The world is not just compressive it is also shear.
Shear upon impact is like breaking all the balls when playing pool. Energy goes everywhere and into the next material boundary..
Try this on.
Your fuse element is included..its there if you have eyes and a mind.
