Any chance these things can "control parasitic vibrations that occur
on top of a speaker cabinet. These resonances negatively impact
speaker performance, specifically the lobbing action in tweeters"?

"Now let's talk about the Beaks.
Vincent Bruzzese says that the design of the Beaks was determined
with the help of a mainframe computer, and that every aspect of it (the
cutout on the underside and the fine grooves milled into the surface)
must be exactly the way they are. He adds that actual frequency
measurements have been run on speakers with and without Beaks, but he
has supplied neither the methodology nor the actual measurements"

It's fraud, but if the Beaks are placed very close to the front of a narrow
cabinet, in close proximity to the tweeter, there would be a change in the
frequency response. An article in this month's Stereophile gives an
excellent intro into cabinet edge diffraction, which is relevant in this
case.

However, the "every aspect", allegedly detailed design, or the uniqueness of
the design, is of no relevance. The effect of these dense, bullet shaped
objects is to modify the effective shape of the upper edge of the baffle,
provided, of course, that they are placed close to the baffle. A wood block
contoured to match the enclosure would work better, although the horizontal
edges of the speaker cabinet are far more important, and left unremedied.
