They are marketed as diffusion. Are you claiming that diffusion as
a means of better sound is a dubious claim or are you saying that
these particular devices don't work?

While I am not the one raising the point, Shakti makes no claims about
diffusion. Rather there "claims" are of the natu

"The Hallograph contours the frequency, amplitude and time
coefficients of the first reflections you hear, which produces
a stunning increase in realism."

Anyone who IS engaged in the research of the behavior of acoustics in
rooms quickly realizes that this statement is so much nonsensical
gobbledygook.

They further claim:

"Activated panels generate a musically complimentary reflective
energy that transforms your listening room by overshadowing
typical room distortions which muddy the bass, overbrighten
the presentation and blur the soundstage."

They appeal to scientific "sounding" terminology like "frequency,
amplitude and time coefficients" without, apparently, having the
faintest clue of what they are talking about. Beyond that, their
claims regarding bas frequencies are rather dubious and overstretched,
considering the wavelengths of bass frequencies and the physical
size of these devices. In their claim that they "overshadow typical
room distortions," this constitutes a truly extraordinary claim,
in essence because they are claiming that these devices, having,
at most, a total frontal area of a couple of square feet, must be
re-radiating more energy than they receive, to account for their
extraordinary ability to "overshadow" the entire combined surface
area of the rest of the room.

Frankly, it's not up to anyone to show that these devices DON'T work,
it's up to Shakti to demonstrate that they do, and that their claims
are supportable. And, to date, Shakti has fallen way short of the
mark in deomstrating that their other products do as they claim, the
ringing endorsements of customers notwithstanding. Frankly, the
recording industry is populate with more than its fair share of
cranks and kooks. Yeah, some of them make GREAT recordings, but an
unfortunately large number of those that do have NO idea HOW they do
it. And a lot of those who have made GREAT recordings have made perfectly
horrible recordings as well.

No, it's not about whether diffusion does or does not work, because
Shakti's thingy has NOTHING to do with diffusion. It's about magic
wands.
