Shakti Hallograph Sound Field Optimizer

I will go this far to say that anything you place in a room will effect sound. Placing plants,glass bottle collection,Lps and Cds and even a ceiling fan all make a difference. For the price Shatki is going for. I believe good acoustic treatment is a far better investment.And proved to work in all rooms.

The Hallographs can make a noticeable and positive difference, depending on your room. Three other members of our local audio group tried these in their rooms and did not hear any difference, then they came to our listening room where we did hear an improvement. My comments on what we heard here are posted here:

Schipo is right. I borrowed a pair and gave them back after using one then both, moving them around. It took about ten minutes to realize that (especially at their price) they are a ripoff. Room treatments work better and are alot less in cost.
