acoustic system resonators

A certain amount of skepticism is a healthy thing, but too much can make us blind to new things. Ah, where is the balance grasshopper?
These things may work, I will not judge them until I experience them myself. A priori judgements only reflect prejudice and preconceived notions.
Those of you who are closed to the idea, have experienced the resonators?

I know absolutely nothing about them, but is a show environment the best place to critically evaluate anything?
And no, I don't want to buy the Brooklyn Bridge, too old fashioned looking for me. I like retro but not that retro plus I dont have the space for it right now.

If I believe only things that I understand then my belief system would be very limited. The reality is; we all believe things we don't understand all the time. I don't know if these things work or not. I'm only stating that I will with hold my opinion until/if I experience them. It just seems to me that prejudging them is meaningless. Now if you've experienced these things and feel that their effect is voodoo then that's another matter so my apologies to Kr4. There are others however that found them effective. They are pretty little things though.
