When the longitudinal wave of a bending wave speaker hits any boundary the wave becomes a shear wave with 2 polarities at least 1 of the polarities will be returning and interfering with the next wave launch.
This same interference displays the same return on a record thru the vinyl and surface. Shear constantly moves between the paper label center and record lip.
The stylus plays the recording and the returning echoes are mixed with the music the stylus must translate but not totally..Another incidence of interfering energy. There are a couple of devices I see reducing the interference. Tom
