What is the Silliest Accessory You Have Ever Seen.

I’m only slightly ashamed to admit that I recently bought a Schumann frequency generator, albeit one of the cheap models.  
I’m always willing to be wrong, and hey, I bought it, but it does seem to me to be one of the more scientifically dubious tweaks.

But for less than fifty bucks, I have a nice little wood box with a red light!  And heck, maybe it does something...

@daveyf point taken. But then what justifies the $1,700 cost? For, in essence, a few pieces of curly wood on a stand?

"But then what justifies the $1,700 cost? For, in essence, a few pieces of curly wood on a stand?"

Someone's willingness to buy it?

@simao One could ask the same question about what justifies the cost on numerous pieces of gear in this hobby!
If you look at how the Shakti’s are made and what goes into the various aspects of the product to get it to market, I can see where they are coming from with the price, certainly at least as much as a ton of other gear that carries pricing that at first look seems "over the top" ( and most times certainly is). The Shakti’s work well as acoustic treatment...more than can be said for a lot of other gear that is also pricey, and offers less for the $$.

"The Hallograph contours the frequency, amplitude and time coefficients of the first reflections you hear..."

What does "contours the frequency" actually mean? Or contouring amplitude and time coefficients, for that matter. How do coefficients get contoured? Aren’t they just numbers?

Whatever it means, how does it contour the frequency when there are many many frequencies involved, as well as many many different room shapes and wall materials? How does it know what to do and to what extent?

"* Activated panels generate a musically complimentary reflective energy..."

What are "activated panels"? How are they activated and how long do they stay active? Is there a re-activation needed after a certain period? Where on the picture are those panels anyway?

These answers should be easy to obtain and verify as that would go with company’s goals...

"Our long-term goal is to continue to provide low cost, easy to use and scientifically verifiable performance enhancement products for the discriminating hobbyist."

Of course, if $1700 is low-cost is on each one of us to decide for her/himself.

EDIT: To make it fair, the cost on Shakti website is only $1500 so we may need to take that into account when discussing "why so expensive".
