Have you heard or own the Shakti Hallograph

Quotes are Shakti's.

""Our stand, which is 4 feet in length, is also asymmetrical and does produce some audible improvement in bass clarity. Again, the goal is to push the room's enormously distorting effects further into the background with a far more neutral ambient soundfield. The reflector material in the Hallograph consists of several types of wood that all have different resonant signatures. All the wood lengths are staggered on the three reflectors. Each reflector has a flat surface that gently curves into a round-over section. These interlaced but geometrically different surfaces have a striking effect. The Hallograph's own direct return energy (from the flat portion of the reflector) and its ambient signals (from the curved reflector area) impact the sonic envelope one hears. This ratio of direct to ambient surface tuning, just as is the case in a concert hall, restores a more natural hall acoustic. So, the inherent differences from recording to recording are no longer stamped with the listener's room signature. Instead, the various original venues are heard far more realistically. Behind each reflector is a chamber that modifies the frequency response, amplitude and most importantly, the time signature of the reflector. This creates a complimentary interface between the speaker and the room."

What do you mean when you talk about the time coefficient?
"This is also known as the time signature; how long a given material goes on ringing once it is activated by sound waves striking it. In the chambers behind each reflector, we 'treat' the time signature so it has a much shorter ring than the material a room's walls are made of. This treatment also affects the frequency response, which has a direct correlation with the time signature character. Amplitude is manipulated by the choice of wood, diffusion geometry of the design and additional treatment that will be explained in the patent."

Additional treatment? Hmmmmmm......

Elizabeth, Shakti Hallographs are only $1395/pair all day long over on Amazon. Maybe you should reconsider. Lol

I own a pair. Of course I don't consider myself a "sucker, idiot, or rich ", since I only paid $500 for mine---had I paid full retail, I guess I would have metamorphed into one.

Before I bought them, or were even interested in them, I had a chance to hear a system with them installed. The system owner become intimately familiar with what the adjustments would do within his system. He demonstrated what the changes would do. I heard considerable differences for the better . To date he has one of the finest sounding systems i have heard. He eventually became a writer for Stereophile. His current system has all the tweaks people bemoan, for good or bad, his system far beyond any system I have heard. His system is the basis for where I try to get my current system to.

I found my pair off Audiogon for $500. If anyone is in the Bay Area, I'd be willing to demo them for you to see if you can see what a difference they can make.

i have a pair and used them until my room did not need them anymore. They absolutely have a strong impact on the soundstage and i think they were worth the investment. like so many things on this forum, people offer strong opinions with no experience with the product.

Agree with this post. I don't use them but have heard them demonstrated at audio shows and they are absolutely audible. Worth the money? That's up to the buyer.
